Lesson Steps

Step Type Explanation Answer

1

Problem

Division of integers:
\$ (- 81) ÷ ( + 9 ) \$

2

Step

The two integers are

\$ - 81 , 9\$

3

Formula:

After applying the rule for the division of negative and positive signs, we obtain the negative sign

\$ ( - ) ÷ ( + ) = (-) \$

4

Step

Let us divide both the integers

\$- 81 ÷ 9 \$

5

Step

After dividing we get

\$ - 9 \$

6

Step

Therefore, the division of integers is \$ - 9 \$.
