To determine

To find sum or difference of 26+(−19) .

Expert Solution & Answer

Answer to Problem 67E

Explanation of Solution

Given information: 26+(−19)

Calculation: This answer shall be derived using the negative and positive signs. If there is addition or subtraction of two numbers with different signs, subtract the numbers having opposite signs. The final answer shall have a positive or negative sign on the basis of the sign that the larger number.

Given, 26+(−19)

=26−19 Here, 26 is the larger number, and it is of positive sign. The smaller number is −19 . Hence , subtract the two.

=5 This a positive value since 26>19
