4(5) + 5(6) - (-4/-2)
.
just to help keep the signs straight, but there is nothing wrong with the way you did it.
.
Now you can just start simplifying ... term by term. Multiply the 4 times the 5 and you get:
.
20 + 5(6) - (-4/-2)
.
Then multiply the 5 times the 6:
.
20 + 30 - (-4/-2)
.
Next divide the terms in the parentheses. -4 divided by -2 is +2 and you have:
.
20 + 30 - (+2)
.
When you remove parentheses preceded by a minus sign, you change the signs of the terms
inside the parentheses. So - (+2) becomes -2 when the parentheses are taken out and the
expression becomes:
.
20 + 30 - 2
.
Now add the three terms and the result is +48
.
Hope this clarifies the problem for you. Good job ...
