Because they are tables of the numbers that are the result of "times"-ing a number.
Times tables
Well, darling, 3 times 4 is 12, so the addition sentence that is equal to 3 times 4 would be 12 + 0. But seriously, why complicate things? Just remember your times tables, honey.
There is only one number that equals 52. It is . . . . . (wait for it) . . . . . 52 .
52 times 500 equals 26000 .
None of the times tables equal 31.
52 * 48 = 2,496
52 times 30 is equal to 1560.
100 times 52 is equal to 5200.
5 x 52 = 260
57000 * 52 = 2,964,000
6 * 52 = 312
160 x 52 = 8,320
Five multiplied by 52 is 260.
