An example is: 9*7 = 63
1 x 63, 3 x 21, 7 x 9, 9 x 7, 21 x 3, 63 x 1.
Just divide both sides by 7...
welll first of all 9x7=63 and 7x9=63
122
9
what x3 equals 63 is:21x3=63
what equals 63
63-84 equals = -21
The product is the answer. 7 x 9 = 63 63 is the product.
Easy multiplication by 5: multiply by 10 and half the answer. 0.63 x 10 = 6.3, half of that = 3.15. Job done.
63 is less than 36 because exponents represent repeated multiplication of the base number by itself. So 63= 6x6x6, whereas 36 equals 3x3x3x3x3x3.
