Why Do So Many People Get It Wrong?
The mistake happens when people calculate from left to right without respecting the correct order of operations.
In math, there’s a rule called:
Order of Operations (PEMDAS)
- Parentheses
- Exponents
- Multiplication & Division (left to right)
- Addition & Subtraction (left to right)
Most people forget that multiplication comes before addition.
Step-by-Step Solution
Let’s solve it correctly:
10 + 10 × 0 + 10
Step 1: Do multiplication first
👉 10 × 0 = 0
Now the equation becomes:
👉 10 + 0 + 10
Step 2: Add from left to right
👉 10 + 0 = 10
👉 10 + 10 = 20

Final Answer: 20
