Let's solve each expression step by step using the
order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right). Since there are no parentheses or exponents in these problems, we focus on
multiplication/division first, then
addition/subtraction, going from
left to right.

1) 7 × 6 - 2 + 8
Step 1: Multiply
7 × 6 = 42
Now:
42 - 2 + 8
Step 2: Subtract and add from left to right
42 - 2 = 40
40 + 8 =
48
✔ Answer: 48

6) 12 - 2 × 12 ÷ 3
Step 1: Multiplication and division (left to right)
First: 2 × 12 = 24
Then: 24 ÷ 3 = 8
Now:
12 - 8 =
4
✔ Answer: 4

7) 8 × 3 - 10 ÷ 2
Step 1: Multiplication and division (left to right)
8 × 3 = 24
10 ÷ 2 = 5
Now:
24 - 5 =
19
✔ Answer: 19

8) 9 - 20 ÷ 5 × 2
Step 1: Division and multiplication (left to right)
20 ÷ 5 = 4
4 × 2 = 8
Now:
9 - 8 =
1
✔ Answer: 1
