Can anybody tell me the rules for adding, subtracting, multiplying and dividing?

Question

i have a quiz over this tommorrow and the teacher didn't give us the answers.

Can you tell me?

as in dividing stuff,etc. you get the point!

Answer 1

addition
same signs add the absolute value and give the common sign
e.g.(+)4+(+)9==(4+9)=+13
(-8)+(-9)=-(8+9)=-17
subtraction.change the sign of the number to be subtracted (the subtrahend) and add it to the number from which this number is to be subtracted(the minuend)
e.g.subtract -6 from 5=> 5-(-6)=5+(+6)=11
multiplication:if the numbers to be multiplied are of the same sign the product will be positive and if theyare of different signs the product will be negatine
e.g. -5*-3=+24 and 32*8=256
-3*8=-24 and 9*-5=-45
division:multiply by the reciprocal
-/- or +/+ both will give + and -?+ or +/- both will give -

Answer 2

First, you divide it's number one fact that down the next number and you go right back. Divide, multiply, subtract, and bring down.

Answer 3

If it is for algebra, the answer is PEMDAS. Paratheses, exponents, multiplication, division, addition, and lastly subtraction. This is the order in which equations are to be solved.

Answer 4

if you're talking order of operations it would be multiply and/or divide first from left to right then do your addition and subtraction from left to right.
