A short explanation in English:
Division and multiplication have the same priority, so you solve them from left to right. If someone reads it as 16 ÷ (2×8) without parentheses, they would get 1, but to mean that, the parentheses must be written clearly.
16 ÷ 2 × 8 goes from left to right.
16 ÷ 2 = 8
8 × 8 = 64
So the final answer is 64.
