How are your math skills?

Time to put your math skills to the test

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. 
 
sum test
 

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 detailed 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

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!
