(+4) + (+3) = +7
*Note that the first integer in the question does not change.

The homework is page 46 A. in the yellow math booklet, questions 1-45. Three questions have to be done with algebra tiles.

Algebra tiles are drawn like this:
Yes, you have to draw both of the opposites (positive and negative) and take away the integer that is from the original question.

The next scribe shall be Nikki Lopez.
