# Sums of 10 Calculator

Sums of 10 means if we have two Numbers one is known other is unknown and we do there sum then the result will be equals to 10. Suppose a number is 4 and other number is 'x', if result of their addition is equals to 10 then we can determine other number as:
=>     4 + x = 10,

=>      x = 10 – 4,

=>     x = 6.

So, if two numbers are in sum of 10 then unknown number can be determined. An online tool is also developed for the same which is known as sums of 10 calculator, and using this tool one can find the unknown number from numbers whose sum is 10.
Step to use calculator:
Step 1:
Plug-in value of known number in ‘Enter a Number’ text box.
Step 2: Click ‘Solve’ button and we get value of unknown number in answer box.

Example: Sum of 10: 7 + _ = 10?
Step 1 :  Given 7 + _ =10.
Equation can be written as:
7 +  x = 10,
Now, we have to find value of 'x', subtract seven from both sides.

7 + x - 7= 10 – 7.
x = 3.
