14 doh Im an idiot..... no brackets

[Benzopyrene]

oops I meant 16 forgot my rules!

14

[NSXCIGAR]

The last equation needs brackets...could be either 10 or 14

[PuffDaddie]

could be

10 - Order of operations. No brackets needed.

Over time, mathematicians have developed a set of rules called the order of operations to determine which operation to do first. The rules are:

1. Multiply and divide from left to right.
2. Add and subtract from left to right.

I'll take it as if 'BEDMAS' doesn't apply to shapes.

14 is my answer.

Fun!

10 final Answer

[Habanos2000]

I guessed 14, my son told me 10. I'm going with 10.

[planetary]

Seems like it's got to be 10, at first glance.

[Dozerhead]

I say 14, but I never was good at math.

Brshoppe, and the explanation is correct

10 is the answer. Brackets not required.

You can always check a calculator is correctly programmed by running a simple check. If you type 2 + 3 x 4 and it gives you the answer of 20 - don't rely on that calculator! Most cheap ones will give you the wrong answer of 20.

seems silly.

This equation should be expressed in the order it is written from left to right

so 20 would be correct

As to the question 10 is correct

Mathematics has rules.

Mathematics has rules.

common sense being at the top of the list......

Fun to see how this basic math (is it 3rd year, elementary school?) really can be subject of so much debate.
