Does -x always represent a negative number why or why not?
Oh honey, let me break it down for you. The expression -x represents the opposite of x, which is usually a negative number because it's moving in the opposite direction on the number line. But hey, if x happens to be 0, then -x would be 0 too. So technically, -x doesn't always have to be negative, but most of the time it is.
Is a positive number and a negative number will always be negative?
A positive number multiplied by a negative number will always result in a negative number.
Can one number represent an algebraic expression?
Yes it can
When a negative number is subtracted from a positive number is the difference always positive?
Yes, a negative number subtracted from a positive number will always be positive. Subtracting a negative number is the same as adding the opposite of the negative number. The opposite of a negative number is always positive. A positive number plus a positive number is always positive.
Which whole number does the expression represent 2.7x10 6?
It is 2700000.
Explain why x does not necessarily represent a positive number?
x may not always represent a positive number because there are equations that make a variable a negative number

How do you work out how to times a positive number by a negative number?
A positive number times a positive number will always get you a positive number A negative number times a negative number will always get you a positive number (same signs will get you a positive number) but A positive number times a negative number will always get you a negative number or A negative number times a positive number will always get you a negative number (different signs will get you a negative number)
What is an expression for 20 times a number?

When is there no solution possible to an absolute value equation and why?
For example: | x | = -1 Or any other equation where the absolute value of any expression is negative. This doesn't have a solution, because the absolute number of any expression is always positive, or zero, never negative.
When does a negative number plus a negative number equal a negative?
Always.
