How are your math skills?

By Boyd01 May 2014

How are your math skills? Time to put it to the test! In this article you can see a math problem, waiting for you to be solved. 

Answer:

When doing a math equation without parenthesis, the order of operations is:

  1. Exponents
  2. Multiplication(/Division)
  3. Addition(/Subtraction)

The first step here is 7/7=1 and 7X7=49.

The second step 7+1+49-7=50

So the answer to this question should be C (50).

For those who got it correct, congratulations, you understand "rules of operations." For the rest, hopefully this was educational!

 

A quick tip for the Order of Operations: BODMAS

Below you can find a detailled BODMAS explanation.

B             Brackets first

O            Orders (powers and square roots, etc.)

DM        Division and Multiplication (left-to-right)

AS          Addition and Subtraction (left-to-right)

Divide and multiply rank equally (and go left to right). Add and subtract rank equally (and go left to right).

 

Example: 3 + 6 × 2

Multiplication before addition:

First 6 × 2 = 12, then 3 + 12 = 15.

 

Example: (3 + 6) × 2

Brackets first:

First (3 + 6) = 9, then 9 × 2 = 18.

 

Example: 12 : 6 × 3 : 2

Multiplication and division rank equally, so just go left to right:

First 12 / 6 = 2, then 2 × 3 = 6, then 6 / 2 = 3

 

Time to put it to the test:

If you follow the BODMAS technique you will find that the answer is C (20).

Use the BODMAS technique and you will never go wrong!
