Answer and explanation:
Multiplication: The multiplication comes from the fact that for -3(-3 + 2) - 6, we distribute -3 to each term in the parentheses and thus multiply:
-3 * -3 + -3 * 2 - 6
Thus, for this step, drag 9 + -6 - 6 into the "perform multiplication" box (the second white card on the picture):
Simplify: Now we perform the operations from left to right to simplify:
9 + (-6) - 6
9 - 6 - 6
3 - 6
-3
Thus, for this step, drag -3 into the "simplify" box (the first white card on the picture):
I attached a picture with arrows that also shows where to drag everything.
