Question

1. $3 - ((-3) - 2 + 10)$
2. $-\frac{7 \times 3}{3} + 8$ $\frac{-21}{3} + 8$

Explanation:

Problem 25: \( 3 - ((-3) - 2 + 10) \)

Step 1: Simplify inside the parentheses

First, calculate the expression inside the parentheses: \( (-3) - 2 + 10 \).
\( (-3) - 2 = -5 \), then \( -5 + 10 = 5 \).

Step 2: Subtract the result from 3

Now, \( 3 - 5 = -2 \).

Step 1: Simplify the fraction

First, calculate the numerator of the fraction: \( 7 \times 3 = 21 \), so the fraction becomes \( -\frac{21}{3} \).
\( \frac{21}{3} = 7 \), so \( -\frac{21}{3} = -7 \).

Step 2: Add 8 to the result

Now, \( -7 + 8 = 1 \).

Answer:

\( -2 \)

Problem 27: \( -\frac{7 \times 3}{3} + 8 \)
