Answer:

Joseph's solution is wrong.

Correct solution:

3 (-2-2) = 3(-4) = -12

-2-2 became -4 because this part of the expression the second 2 carries the subtraction sign and becomes a negative number. And math rules say that when subtracting two numbers that are both negative numbers, addition is applied instead of subtracting and the negative sign ( - ) is carried along with the sum.

Then, when multiplying a positive number which is the 3 with a negative number which is the -4, the resulting product will carry the sign of the greatest digit (-4).
