Order of operations
A term may be a product like 5 × 2. Evaluate each term (its × and ÷) before adding or subtracting. This grouping is what makes 2x a single term.
Why it works
A term is a little package; × and ÷ live inside it.

Multiplication and division bind tighter than addition and subtraction. So in 4 + 5 × 2, the 5 × 2 is a single term worth 10. This is exactly why, later, 2x is one term.

5 + 6 × 6
Step
6 × 6 = 36
Step
5 + 36 = 41
14 ÷ 2 + 3
Step
14 ÷ 2 = 7
Step
7 + 3 = 10
10 × 5 - 6
Step
10 × 5 = 50
Step
50 - 6 = 44
Going strictly left to right: 4 + 5 × 2 = 18.
No — × first: 4 + 10 = 14.
