To turn a problem from multiplication to division you have to do the opposite of division to multiplication. You have to change the symbol and then divide. Example math 5*2 =10 math is the same as math 5\div\frac{1}{2} math you have to change the sign

and that equals 10

__**Changing Addition to Subtraction**__
by: Eric

To change addition to subtraction what you have to do is leave the starting number the same but change the sign of all numbers after that to the opposite sign. Also change the addition sign to subtraction because subtracting a negative is just the same as adding a positive so the sum will still remain the same.

Example : 4 + 5 = 8 4 - -5 = 8
