You can tell it will be even when the number you are multiplying has a 2 4 6 8. You can tell it will be odd when the number you are multiplying has a 1 3 5 7.
After you add or subtract two rational expressions its a good idea to see if you can your answer?
You should check whether you can simplify the answer.

Why is it important to always subtract the earlier value from the later value when finding the change in mass instead of always subtracting the smaller value from the larger one?
If you always subtract the smaller value from the larger one, the number that you tell other people lets them know how much the mass changed, but it doesn't tell them whether the mass increased or decreased as time passed.

What do you do when you're going to subtract fractions but the numerator is the same?
its the same as working with integers. + and a + = + -and a - = + + and a - = - - and a + = - eg. 4/4 - - 3/4= 4/4 + 3/4= 1 3/4 1/2+ - 3/10 = 2/10= 1/5
What is the highest digit that will make 980 divisible by 6?
It depends on whether you mean the highest digit that you add or subtract or multiply by!
How do you find volume for cylinders with 7cm?
The volume of any cylinder can be found by multiplying the value of Pi by the radius squared, then multiplying by the height. Since you didn't specify whether the 7cm measurement was the radius or diameter - you will have to do the calculations yourself based on the information in this answer !
