123456 8 + 6 = 987648 + 6 = 987654 1234567 8 + 7 = 9876536 + 7 = 9876543 Yes, the pattern works. As 123456 = 111111 + 11111 + 1111 + 111 + 11 + 1, 123456  8 = (111111 + 11111 + 1111 + 111 + 11 + 1) 8                    = 111111 8 + 11111 8 + 1111  8 + 111 8 + 11 8 + 1  8                    = 888888 + 88888 + 8888 + 888 + 88 + 8                    = 987648 And, 123456 8 + 6 = 987648 + 6 = 987648

If the product of 2 numbers is 1, then both the numbers have to equal to 1. For example, 1 x 1 = 1 However, 1 x 6 = 6 Clearly, the product of two whole numbers will be 1 in the situation when both numbers to be multiplied are 1.

If the product of 2 whole numbers is zero, then one of them is definitely zero. For example, 0 x 2 = 0 and 17 x 0 = 0 If the product of 2 whole numbers is zero, then both of them may be zero. 0 x 0 = 0 However, 2 x 3 = 6 (Since numbers to be multiplied are not equal to zero, the result of the product will also be non-zero.)

We can represent a number by two rectangles. for example 12 = 3 x 4 or 2 x 6 five other such examples are : 24 = 12 x 2  or 24 = 6 x 4  18 = 9 x 2 or 18 = 3 x 6 15 = 15 x 1 or 15 = 3 x 5 30 = 10 x 3 or 30 = 5 x 6  40 = 10 x 4 or 40 = 5 x 8.
