John earned three dollars for each lawn he mowed. if he had eight lawns to mow, but forget mow two of them, how much money did he actually earn?

If John had to mow 8 lawns, but he forgot to mow 2 lawns, we have to subtract 2 from 8 to see how many lawns he actually mowed.

8-2=6

John mowed 6 lawns!

For each lawn John mowed, he earned 3 dollars. So, we have to multiply the number of lawns he mowed, 6, by the amount of dollars he earned per lawn, 3. Multiplying 6*3 is the same as adding 3+3+3+3+3+3!

6*3=18

John earned $18!

Hope I helped! :)
