More-think of it like a ladder. You have o then upward numbers starting with one on the other side you have the negative (downwards) numbers also starting with one. Just remember there is a one on either side of zero and they go naturally in same sequence. A number that is not as far down the bottom is bigger. Just think of it as the smaller number being "less negative" so it's worth more.
12 is 3 less than 15.
-15 is less than 12
Multiple of 4 less than 15
15x - 12
12.
15.x-12
3 It is 12 more than -9 and 12 less than 15 9 + 15 = 24 24/2 = 12 -9 + 12 = 3 15 - 12 = 3
x is less than or equal to 15
15
The only two integer numbers greater than 12 and less than 15 are 13 and 14. Of these, only 14 is even. Therefore, the answer is 14.
The median of the 12 primes less than 40 is 15.
Yes.
