Subtract and the Keep the sign of the one that has more
Subtract the number you first thought of.
to subtract an integer, add its opposite or additive inverse.
You subtract the smaller from the larger.
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 two numbers with different signs means subtracting the two absolute integers (without sign) and vice versa.
turn the subtraction sign into an addition sign and the 3 into a negative: 1+-3=-2
To add two integers with opposite signs . . . -- Ignore the signs, and write the difference between the two numbers. -- Give it the same sign as the larger original number has.
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.
signs are different.... Find the difference.... KEEP THE LARGER SIGN signs are the same... COMBINE AND KEEP THE SIGN
