Adding integers, if they have the same sign, add their absolute values and keep the same sign. Subtracting, change the sign of the 2nd number and the add using rules of addition. Multiplying and dividing, Divide the absolute values, if the signs are the same the answer is positive, if the signs are different the answer is negative.

numbers with Like signs : result Plusnumbers with Unlike signs : result Minus

1. change the subtract to an add and switch the sign of the second. 2. follow rules for addition. -same sign is adding and keep the sign -different sign is subtract and take the sign of the bigger number

ADDING: same sign, add and keep that sign. opposite sides, subtract their absolute values and use the sign of the number with the larger absolute value SUBRTRACTING: change the sign of the subtrahend (2nd number) then ADD using rules above.

To add integers with like signs you jut put the positive in front of the answer (you just add and put a positive sign in front of it)

Rules: Unlike SignsSubtract the absolute value of the number and copy the sign of the number with greater absolute value.

well, if it is a negative plus a positive, it would be much like subtracting backwards, like this: -4+7=3 or -11+7=-4 also, if it is a positive plus a negative, you subtract 4+(-7)=-3 or 11+(-7)=4

adding1. like sign, add their absalute value & copy the common sign.2. unlike signs. subtruct their absalute value & copy the sing of the bigger number.subtructing1. change the sign of the subrahend (if + change to - & if - change to +)2. then go back to the rules in addition.multiplying & dividing1. likes signs, simply perform the operation then the answer's sign would be (+) positive2. unlike signs, simply perform the operation then the answer's sign would be (-) negative

the minus sign is used for subtraction in math. it shows that you are subtracting

To add numbers algebraically means that you consider the sign, using the common rules of algebra. For example, adding (-5) is the same as subtracting the number 5.

they are both the same because you get the same answers you just drop the \$ sign. Ex. \$3.56+\$1.50=\$5.06 and 3.56=1.50=5.06

The answer has the sign of the number which has the greater absolute value.

Addition is shown with a plus sign (+), subtraction is denoted by a minus sign (-).

One rule is that the product of two integers with unlike signs will have a minus sign for the product.

For each pair of such integers, find the difference between the absolute values of the two integers and allocate the sign of the bigger number to it.

When subtracting negative numbers change the subtraction sign to a plus and change the second number (which would appear to be positive) to a negative. ex. -14 - 7=?/-14 + -7= -21 When adding negative numbers just add them as they appear. ex. -2 + -5= -7

if substracting by two negatives your going to add ex: -2-(-5) it would be positive 7. if your substracting with two differ numbers it you would substract and take the sign the sign of the biggest number.ex: 2+(-3) it would be-1 sice 3 is bigger than2 you take the sign of 3

Subtract and the Keep the sign of the one that has more

No.For the sum of integers:-- two positives make a positive-- two negatives make a negative-- the sum of mixed signs is the sign of the one with the greater absolute valueFor the product of integers:-- like signs make a positive-- unlike signs make a negative
