Let E1 and E2 be two even numbers. Then (E1+1)(E2+1) will be the product of two odd numbers. We have E1*E2 +E2+E1+1. Now when we add or multiply even numbers, we get even numbers and we add 1, it's odd.
Well you can multiply 2 and 2 and it will give you 4 when u add

Multiply the three-digit number by the one's digit, or last digit, of the two-digit number. That is your first part. Now multiply by the second-to-last digit, or ten's digit, and multiply the result by 10. That is your second part. Add the two parts and that is your answer.

You add two fractions with a different denominator by multiplying the denominators by a number that will make them equal. Be sure to multiply the numerator by that number too.
First, multiply the original number by 10. Then multiply the original number by 2. Add the two answers that you got and you have just multiplied by 12. For Example: 7x12=(7x10)+(7x2) 70+14 84
