How can you tell without any calculations whether a number ending in 5 is a prime or composites number?
If it is 5 it is a prime. If it is any other positive integer ending in 5 it is a composite.
What is the sum of a positive integer and a negative integer negative?
This depends on the relative magnitudes of the integers. The magnitude is the value of the number (without the sign). Or another way to look at it is how far away from zero is it. So if the positive integer has a greater magnitude, the sum will be positive. If the negative integer has the greater magnitude, then the sum is negative.Say, for example, your car is parked at the Equator (call this zero). Now drive 5 miles in the North (positive) direction. Now turn around and drive 4 miles in the South (negative) direction. You end up 1 mile North of the Equator, which is positive.If you start again driving 5 miles North, then drive 8 miles South, you end up 3 miles South of the equator (negative).Note that it doesn't matter which one you do first (if you drive 8 miles South first, then 5 miles North, you're still ending at 3 miles South of the Equator). This demonstrates the Commutative Property of Addition (the order can be rearranged and get the same answer).
Is a hydroxide ion positive charge?
No. The hydroxide ion has a negative charge as do all ions ending in -ide, -ite, or -ate.

Is any number ending in zero divisible by four?
Yes, but the quotient will not always be an integer.
Is 8 an odd number?
Any integer ending in 1, 3, 5, 7, or 9 is an odd number. Any integer ending in 0, 2, 4, 6, or 8 is an even number. Therefore, 8 is an even number.
