[solved]Doubt during challenge

Question

Probably it's a dumb question, but during a challenge this question showed up and the correct answer is 65... How? 🤔😓
Could someone explain to me how to get this result?
Of course I answered wrongly 225.

Answer 1

The thing here to be noted is operator precedence. * has higher precedence than +.
In expression, 10 + 5 * 10 + 5,
Multiplication is evaluated first. So it will be 10 + 50 + 5. Now normal addition will be performed and answer will be 65.
