You don't. You can check addition with subtraction or subtraction with addition, since subtraction is the opposite of addition. Similary, you can check division with multiplication, or vice versa.

Do (multiplication/division) before you do (addition/subtraction).
It depends whether it is a subtraction, mulitplication, addition, or division problem.
Division
Multiplication is successive Addition Division is successive subtraction
Division
Solving this equation for x actually requires subtraction and division rather than addition and division.
Subtraction is used to check addition.
I assume you mean the 'Order of Operations' which are: 1 Brackets 2 Exponents (Powers and Roots) 3 Multiplication and Division 4 Addition and Subtraction Therefore, division will be done before addition.
to ensure and re-check your work you use the opposite signs (addition & subtractions, multiplication & division) e.g. __= blank 10+ _ = 12 _=2 to check: you take the answer (in this case 12) and subtract (because its the opposite of addition) by the blank you filled in (2 in this case. therefore, 12-2=10 so we know its correct :-)
nope. Multiplication is a form of addition. Division is a form of subtraction.
the fundamental operations in math are, addition +, subtraction -, division /,and multiplication x ..
