The distributive property also combines subtraction and multiplication. For example, 3 x (5 -2) = (3 x 5) - (3 x 2). Explain how you could use the distributive property and mental math to find 5 x 198.

One way would be to split 198 into components you could multiply by 5.  Like 100+90+8.  Then, 5(100+90+8) = 500+450+40 = 990
