Answer 2

Answer:

Step-by-step explanation:

Given: the numbers 256 and (- 312)

To find: the sum of 256 and (- 312)

Solution:

Before we find the sum of two numbers, we must remember that when a positive symbol is multiplied with a negative symbol, we get a negative symbol.

i.e., ( + ) × ( - ) = ( - )

Now, the sum is

= 256 + (- 312)

= 256 - 312

= - (- 256 + 312) [ taking negative symbol common ]

= - ( 312 - 256) [ rearranging the terms)

= - 56
