In Ancient Rome, Ancient Greece, Ancient Israel, Ancient Egypt, record keepers used a range of alpha (or some other character) to specify individual numbers. And for measuring purposes, the abacus, with its use of smooth stones in a base-10 counting frame was widely used at the time of Christ. It's use is in fact inferred in the Lord's question: "Which of you intending to build a castle does not first sit down and count (via these pebbles) the expense for whether you've got what it's going to take to complete it?" See
In Ancient Babylon, a positional column setting using a base-60 set of numbers were used. The right column covered numbers 1-59, next column to the left covered (1-59)*60, and so on. If a fraction was necessary, a further column would be set up on the right. A zero value was indicated by leaving a space in that column. Division was done by multiplication, using the number's reciprocal (as set out in tables).
This base-60 system was useful for measurements of time (minutes and seconds), and also space (the 60 degree angle used in 6 equilateral triangles set out in a hexagon could establish perimeters and areas for any point on the compass). See the image below for these Babylonian numerals.

Finally, click here for the base-10 set of Arabic numerals. These "Hindu" numerals as Persian polymath al-Khwarizmi (Al'gorithmi) called them with his publishing of a book on algebra (al-jabr), back around 820 AD, then spread through the Perso Arabic world.
Decimal fractions were seen about 952 AD, with scholars using a bar over the units digit, e.g. 9995. Commonly seen today as an underbar to superscript digits when printing monetary values e.g. 9995. Later, a "separatrix" (a short, roughly vertical ink stroke) between the units and tenths position became the norm among Arab mathematicians (e.g. 99ˌ95), while an L-shaped or vertical bar (|) served as the separatrix in England.
These "Arabic" numerals were adapted by scholars in the West after 1202, importantly Leonardo Pisano (Fibonacci), followed by Sacrobosco at the University of Paris — and after the late 1500s came into regular use worldwide.
Now, why that long delay ? In fact in Florence (top trading centre in the west in 1299) bookkeepers were forbidden the use of these new Arabic numerals.
And so the west had to wait for the invention of the printing press in Germany around 1440, and seeing their useful application when printing verse numbers in the Bible in the late 1500s, before Arabic numerals achieved widespread acceptance.
Finally, something they could agree on. α
αOne point though, before the printing press, the period character was used in Roman numerals to separate thousands from hundreds, and hundreds from units, in France and on the continent. But in England Scotsman John Napier printed a book on logarithms in 1614, using the period character to separate whole numbers from decimals, apparently the first major writer to do so. And in 1711, we see it in English as the "Decimal Point". On the continent, somewhat confusingly, they continued to print the traditional comma there
βOne exception to writing whole words instead of letters for numbers in the Greek New Testament is that famous passage in
Extract from Josephus chapter 3 paragraph 9: "But let no one upon comparing the lives of the ancients (Adam to Noah) with our lives, and with the few years which we now live, think that what we have said of them is false; or make the shortness of our lives at present an argument that neither did they attain to so long a duration of life. For those ancients were beloved of God, and lately made by God himself; and because their food was then fitter for the prolongation of life, (they) might well live so great a number of years. And besides, God afforded them a longer time of life on account of their virtue (manliness), and the good use they made of it in astronomical and geometrical discoveries".

Josephus also attributes to Abraham the office of being a maths teacher, an astronomer and a diplomat (as well as being that of a shepherd), wisdom he had gained in the Chaldees where he was born. He passes on this mathematics knowledge to the Egyptians, for yes, it had been 430 years since the flood - see timeline, and this knowledge had been lost in Egypt (as well as in Greece). It is now the Middle Kingdom, and pyramid building restarts.
Extract from Josephus chapter 8 paragraph 2: "For whereas the Egyptians were formerly addicted to different customs, and despised one another's sacred and accustomed rites, and were very angry one with another on that account, Abram conferred with each of them, and, confuting the reasonings they made use of, every one for their own practices, demonstrated that such reasonings were vain and void of truth: whereupon he was admired by them in those conferences as a very wise man, and one of great sagacity, when he discoursed on any subject he undertook; and this not only in understanding it, but in persuading other men also to assent to him. He communicated to them arithmetic, and delivered to them the science of astronomy; for before Abram came into Egypt they were unacquainted with those parts of learning; for that science came from the Chaldeans into Egypt, and from thence to the Greeks also".
Eratosthenes — click to view further details — a Greek astronomer who lived in Alexandria in 230BC and demonstrated the circumference of the Earth without leaving Egypt.
Eratosthenes knew that on the summer solstice at local noon in the Ancient Egyptian city of Swenet (known in Greek as Syene, and in the modern day as Aswan) on the Tropic of Cancer, the sun would appear at the zenith, directly overhead (he had been told that the shadow of someone looking down a deep well would block the reflection of the Sun at noon). He also knew, from measurement, that in his hometown of Alexandria, the angle of elevation of the sun was 1/50th of a
Assuming that the Earth was spherical (360°), and that Alexandria was due north of Aswan, he concluded that the meridian arc distance from Alexandria to Aswan must therefore be
From this he may have thus demonstrated that the distance to the sun from the earth was about 150 million kilometres.
There were later disagreements about his calculations regarding the circumference of the earth, and Christopher Columbus took the lower estimate as seen on the map he used, of course he may never have got financial approval for his trip if he’d gone with the higher estimate.
