Ignore the signs and subtract the smaller number from the larger one.
if the signs are the same you must add its opposite.
They become positive integers for instance - - 2 = 2
(-10) - (-5) = (-5) when subtracting a negative number from another negative number if the first number is larger that the second number then you just subtract the to numbers. don't worry about the signs just subtract the numbers when your done put the sign of the first number on again.
for integers with tow different signs, it will always be negative in multiplying and division. for adding and subtracting, the sign is for the bigger number.
-- write the difference between the integers without regard to their signs -- give the difference the same sign as the larger of the two integers
-You must memorize -To add 2 integers with different signs, find the difference of their absolute value -To subtract an integer, add it's opposite
To add two integers with unlike signs: -- Find the difference between their sizes, ignoring their signs. -- Give the difference the sign of the integer with the larger size.
The sum or difference will take the sign of whichever number is larger (disregarding the signs). -6 + 8 = 2 6 + -8 = -2 8 - (-6) = 14 -8 - 6 = -14
Adding two numbers with different signs means subtracting the two absolute integers (without sign) and vice versa.
-- If the two integers have the same sign, their quotient is positive. -- If the two integers have different signs, their quotient is negative.
Examples: Write the first integer as it is, turn the subtraction into the addition, change the sign of the second integer, and follow the rules of addition. -7 - (2) = -7 + (-2) = -(7 + 2) = -9 10 - (-8) = 10 + (+8) = 18
