What is the sum of twice a number?

So twice a number means 2x. The sum (use plus symbol) of twice a number and 3 can be written as 2x+3.

How do you calculate twice of a number?

Twice a quantity usually indicates to take two of the things in question; usually this indicates to multiply by 2. Thus “twice a number x” can be written symbolically as 2x. If this is part of a problem, say twice a number x is 6, then we can rewrite algebraically as 2x=6; dividing both sides by 2 yields x=3.

What is twice a number?

“Twice’ simply means “multiply by 2”. In algebra we usually do not know the values of the numbers we are working with, we just call them variables and use letters to represent them. IN this case the number we are talking about is x . In the same way as twice 3 is written as 2×3 , T.
