1. The problem is to simplify the expression $(6 - (-8)) \div (-7)$.\n\n2. First, simplify inside the parentheses: subtracting a negative is the same as adding a positive, so $6 -

1. **State the problem:** Simplify the expression $(-6)^2 \div 4$. 2. **Recall the order of operations:** Exponents are evaluated before division.

1. The problem is to simplify the expression $(–6 – –8)3$. 2. First, simplify inside the parentheses: $–6 – –8$ means $–6 + 8$ because subtracting a negative is the same as adding.

1. The problem is to simplify the expression $-3 + 1 - (-2)$.\n\n2. Recall that subtracting a negative number is the same as adding its positive counterpart. So, $- (-2) = +2$.\n\n

1. **State the problem:** Simplify the expression $2 - 4 \div 4$. 2. **Recall the order of operations:** Division and multiplication are performed before addition and subtraction.

1. **State the problem:** Evaluate the expression $4 + \frac{6^2}{(6 - 2^2)}$. 2. **Recall the order of operations:** Calculate exponents first, then parentheses, then division, an

1. Stating the problem: Simplify the expression $5x2(5x)2$. 2. Understand the expression: The expression can be interpreted as $5 \times 2 \times (5x) \times 2$.
