Use mental math to complete the pattern(5×6)×10=

The answer is 300 because you go 5❌6=30 and then 30❌10=300

I learned that when doing an operation, I should always look is there are any parenthesis in the operation : (5x6) is the operation inside the parenthesis. The answer to this is 30. 5x6 = 30. Then we do the rest. Since our first answer was 30, we are going to multiply that by 10, which would give us the answer of 300.
DREAMEDINA1 is correct.

Hope this helped!!!
