Problem

Addition of integers:
\$ 22 + (- 91) + 13 + 71 \$

Hint

The integers are

\$ 22,- 91,13 and 71 \$

Formula:

Here we apply the rule of addition of positive and negative integers

\$ (+) + (-) = "use the sign of larger absolute value number" \$

Step

Let us add the positive and negative integers

\$ 22 + (- 91) + 13 + 71 \$

Step

After add the positive and negative integers

\$22 - 91 + 13 + 71 \$

Step

After simplification

\$+ 106 - 91 \$

Step

After adding

\$ 15 \$

Step

Therefore, the addition of integers is \$ 15\$.

Choice.A

This choice is inaccurate as the total amounts to 15, rather than the expected 17

Choice.B

This precise selection sums up to a total of 15 with the given numbers

Choice.C

This representation is inaccurate because it only considers the initial number and not subsequent additions

Choice.D

This representation is inaccurate; the sum of the provided integers is positive 15, not negative 12

-12
