3.(+5)X(-2
13.(-7)X(-2)
4.(-5X(+2)
14.(-7)X(+2)
5.(+7)X(+3)
15.(+7)X(-2)
6(-7)X(-3)
16.-8/-2.
please solve this question and explain please ​

Answer 1

Answer:

(+5) X(+2) = 10

(+9)X(-4) = -36

(-5)X(-2) = 10

(-9)X(+4) = -36

(+5)X(-2) = -10

(-7)X(-2) = 14

(-5X(+2) = -10

(-7)X(+2) = -14

(+7)X(+3) = 21

(+7)X(-2) = -14

(-7)X(-3) = 21

-8/-2 = 4

Explanation:

• If 2 positive numbers are multiplied we get the product as positive

eg: 2 × 3 = 6

• If 2 negative numbers are multiplied we get the product as positive

eg : (-4) × (-6) = 24

• If 1 negative number is multiplied to 1 positive number we get the product as negative

eg : (-6) × (+2) = -12

• If 1 positive number is multiplied to 1 negative number we get the product as negative

eg : (+3) × (-2) = -6
