Скачать или смотреть Multiplying several integers (7th grade math/prealgebra)

Let's say we have several integers to multiply, such as 5 x (-2) x (-1) x 3 x (-2). If you pair the negative ones, each pair will produce a positive answer. In the end, if there is an EVEN number of negative numbers to multiply, the result will be positive, and if an ODD number, the result will be negative.

After looking at examples of such, I also find the value of various powers with a negative base, such as (-2)^3 and others.

We also look at enlarging a geometric figure in the coordinate grid. This simply involves multiplying its coordinates by the same number.
