Example 1Find –16 8.You can solve this problem by looking for a pattern.
8 8 = 10 8 = 0
2-8 Dividing Integers
Example 1Find –16 8.You can solve this problem by looking for a pattern.
8 8 = 10 8 = 0-8 8 = -1
2-8 Dividing Integers
Example 1Find –16 8.You can solve this problem by looking for a pattern.
8 8 = 10 8 = 0-8 8 = -1-16 8 = -2
2-8 Dividing Integers
Example 1Find –16 8.You can solve this problem by looking for a pattern.
So, -16 8 = -2
8 8 = 10 8 = 0-8 8 = -1-16 8 = -2
2-8 Dividing Integers
The quotient of two integers with different signs is negative.
2-8 Dividing Integers
Example 2Solve y = 39 (-13).y = 39 (-13) The dividend and the divisor have
different signs.
2-8 Dividing Integers
Example 2Solve y = 39 (-13).y = 39 (-13)y = -3
The dividend and the divisor have different signs. The quotient is negative.
2-8 Dividing Integers
The quotient of two integers with the same sign is positive.
2-8 Dividing Integers
Example 3Solve x = -52 (-4).x = -52 (-4) The dividend and the divisor have the
same sign.
2-8 Dividing Integers
Example 3Solve x = -52 (-4).x = -52 (-4)x = 13
The dividend and the divisor have the same sign. The quotient is positive.
