What is answer

Recommended Posts

Windows Calculator doesn't respect mathematical expressions if you don't tell him priority calculations.

You need to had parentheses so he can understand.

Parentheses have an higher priority then simple math calculations: https://en.wikipedia.org/wiki/Order_of_operations

The answer is 9. you have to solve it from left to right and first that in the clinches:

6/2 * 3

3 * 3 = 9

also doable this way:

6/2 = 3

3 * 1 = a

3* 2 = b

a+b = 9

So parentheses don't have a meaning?

2(1+2) is = (2 x 1) + (2 x 2)

To be honest that is an ambiguity question as it is not using any kind of fraction so both the answers could be taken..

But if you want an answer according to the math standards then the lack of fractions in the formula gives the priority to mathematical patterns, which is "from left to the right" after solving the parentheses
