if I take a number and make it 1 x greater; is it the same number or twice as large?

Answer 1

Think of it like this....

20 is 2 times greater than 10.... and 10 * 2 = 20

Following that logic and reasoning...

10 is 1 times greater than 10 and 10 * 1 = 10

So based on that, it is the same number
