Question

Can someone tell me everything I need to know before a integer test please

Answer 1

Absolute value- the
real number without regard to its sign.

Multiplication- *Negative* x *Negative* = Positive alwayss

Multiplication- *positive* + * Negative* = Negative always (same vise versa)

Division- *Negative* x *Negative* = Positive alwayss

Division - *positive* + * Negative* = Negative always ( same vise versa )

Additon- You do keep change change with this one ( example- -7 + 6 change this too- (-7 - (-6) = -1)
no matter weather its a positive or negative number KEEP THE SIGN OF THE BIGGER NUMBER!

Subtraction- You do keep change change with this one also ( example- 6 - -12 change this too- (6 + (12) = -18)
no matter weather its a positive or negative number KEEP THE SIGN OF THE BIGGER NUMBER!

Hope this helped
