## Q1) Find the solution of the Math Quiz “12 – 1 x 0 + 4 / 2”.

Answer) First learn about DMAS rule if you want to solve such type of simple math expressions.

### What is DMAS & how it can help in solving mathematical expression?

DMAS stands for division, multiplication, addition & subtraction. This rule is used to solve simple expression that contains addition, subtraction, multiplication or division. If an expression has multiple operations, then solve division first followed by multiplication, addition & subtraction. If your expression has parenthesis or exponents, then you can’t apply DMAS rule but use PEMDAS rule instead to solve such type of questions.

### What is PEMDAS & how it can help in solving an expression that has 2 or more operations?

PEMDAS stands for parenthesis, exponents, multiplication, division, addition & subtraction. If 1 expression has 2 or more operations, then follow the order of the letters in PEMDAS to calculate 1st, 2nd, 3rd & so on, until you get the result. If your expression has grouping symbols, then this rule instructs you to calculate within the grouping symbols 1st.

For solving the above math question, I am using DMAS rule. It stands for Division, Multiplication, Addition & Subtraction. According to DMAS rule, I need to solve division first followed by multiplication, addition & subtraction. Check out the solution:

12 – 1 x 0 + 4 / 2    "Solve division"

12 – 1 x 0 + 2    "Solve muliplication"
