Technically, yes, because you can multiply 99 by 1 and still get 99.
The number before 99, that is, 99 - 1.
Sum 1 + 2 ... + 99 + 100 = 5050
When you multiply a number by 1, it stays the same. When you multiply a number by a number greater than 1, it increases. When you multiply a number by a number that is less than 1 (a proper fraction), it decreases.
99 is not a prime number because it has more factors than 1 and itself. The factors of 99 are 1, 3, 9, 11, 33, and 99.
if its 1x1 its 1. If its 99x1 its 99. so whatever number x one equals that number
no
Technically, yes, because you can multiply 99 by 1 and still get 99.
1 x 99 = 99 3 x 33 = 99 9 x 11 = 99

Yes. You can always multiply a number by 1.. and get the number you started with.. so every number is a multiple of itself.
1 x 99 2 x 49.5 3 x 33
The number before 99, that is, 99 - 1.

to multiply a number by 9, the numbers in your answers add up to 9. Here's a pattern: 9*1=9 9+0=9 9*2=18 1+8=9 9*3=27 2+7=9. When we get to 9*11, we get 99. 9+9=18, 1+8=9. The rule still applies to 99.
