Consider the expression 3 * 2 ^ 2 15 - 3. Which operation is performed second?

In the first expression

3 * 4 will be performed second.

In the second expression

10 * 2 will be performed second.

Explanation:

In many programming language, there is an operator precedence where the operator (e. g. +, -, *, / etc) will be executed following a specific order. For example, the operator ^ which denotes power will always be executed prior to * or / and if / and * exist in the same expression, the operator positioned at the left will be executed first.

Hence, in the expression 3*2^2 < 16, 2 will be powered to 2 (2^2) first and then only multiplied with 3.

In the expression 100 / 10 * 2 > 15 - 3, 100 will be divided by 10 and then only multiplied with 2.
