 OFFLINE | 5 times even number
Rules:
Write half of the even multiplier down and put 0 at the end.
Examples:
5 x 2; Half of 2 is 1. Put 0 behind the 1 to form our answer. Hence 5 x 2 = 10.
5 x 12; Half of 12 is 6. Put 0 behind the 6 to form the correct answer. Hence 5 x 12 = 60.
5 times odd number
Rules:
Write half of the odd multiplier down and reject the decimal point. The number you see is your product.
Examples:
5 X 1; Half of 1 is 0.5. Reject the decimal point. Hence 5 x 1 = 5.
5 x 7; Half of 7 is 3.5. Reject the decimal point to get 35. That is your product.
.
5 x 19; Half of 19 is 9.5. Reject the decimal point to get 95. This is your product.
