Answer 2

Answer:

45 + (-28) = +17

Step-by-step explanation:

To find,

Add the integers 45 and (-28)

Recall the concepts

To add a +ve integer and a -ve integer,

• The magnitude of the sum is the difference between the two numbers
• The sign of the sum is the sign of the greatest number in magnitude

Solution:

The difference between the two numbers without sign = 45-28 = 17

The sign of the number with the greatest magnitude = +ve.

∴ The required sum = +17

Hence, 45 + (-28) = +17
