Thomas Fuller, an African who was 14 when he was taken into slavery in 1724, was frequently referred to as the “Virginia Calculator” because of his amazing capacity to figure out challenging mathematical problems in his head. When asked the number of seconds in a year and a half, he replied in around two minutes with 47,304,000. When asked again how many seconds a man who was 70 years, 17 days, and 12 hours old had lived, he responded in a minute and a half, giving the response 2,210,500,800.
One of the men corrected Fuller, saying the answer was considerably smaller, as he was solving the puzzles on paper. Quickly responding, Fuller said, “Top, massa, you forget de leap year.” The sums matched after the leap year was taken into account.
Thomas Fuller, an African, was sent to America in 1724 as a slave. Late in his life, antislavery activists learned about him and presented him as evidence that blacks are not mentally inferior to whites. He possessed impressive arithmetic skills.
His birthplace is thought to have been somewhere between modern-day Benin and Liberia. He was known as Negro Tom, and we know that he was taken to the United States as a slave. He was characterised as a very black man, and he lived in Virginia. He was undoubtedly Elixabeth Coxe of Alexandria’s property at a late stage of his life.

Scripture writes in Thomas Fuller, known as the Virginia Calculator, was stolen from his native Africa at the age of fourteen and sold to a planter. When he was about seventy years old, two gentlemen, natives of Pennsylvania, viz., William Hartshorne and Samuel Coates, men of probity and respectable characters, having heard, in travelling through the neighbourhood in which the slave lived, of his extraordinary powers in arithmetic, sent for him and had their curiosity sufficiently gratified by the answers which he gave to the following questions: First, Upon being asked how many seconds there were in a year and a half, he answered in about two minutes, 47 304 000. Second: On being asked how many seconds a man has lived who is 70 years, 17 days and 12 hours old, he answered in a minute and a half 2 210 500 800. One of the gentlemen who employed himself with his pen in making these calculations told him he was wrong, and the sum was not so great as he had said – upon which the old man hastily replied: stop, master, you forget the leap year. On adding the amount of the seconds of the leap years the amount of the whole in both their sums agreed exactly.
Another question was asked and satisfactorily answered. Before two other gentlemen he gave the amount of nine figures multiplied by nine. … In 1790 he died at the age of 80 years, having never learned to read or write, in spite of his extraordinary power of calculation.
Present day thinking is that Fuller learnt to calculate in Africa before he was brought to the United States as a slave. Supporting evidence for this comes from a passage written by Thomas Clarkson in 1788 describing the purchase of African slaves:-
It is astonishing with what facility the African brokers reckon up the exchange of European goods for slaves. One of these brokers has ten slaves to sell , and for each of these he demands ten different articles. He reduces them immediately by the head to bars, coppers, ounces… and immediately strikes the balance. The European, on the other hand, takes his pen, and with great deliberation, and with all the advantage of arithmetic and letters, begin to estimate also. He is so unfortunate, as to make a mistake: but he no sooner errs, than he is detected by this man of inferior capacity, whom he can neither deceive in the name or quality of his goods, nor in the balance of his account.
Despite Fuller’s calculating abilities he was never taught to read or write and again this is evidence that he did not learn to calculate while in the United States. When someone who had witnessed his calculating abilities remarked that it was a pity he had not been educated, Fuller replied
It is best I got no learning; for many learned men be great fool
