Question

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

Answer 1

You could distribute the 5 to each separated piece of the number.
For example, (5×100) + (5×90) + (5×8)
Then, when you add the sums together you can get your answer. Hope that helped :)

Answer 2

5×100 5×90 5×8 =
500+450+40=990
