(-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.
They become positive integers for instance - - 2 = 2
-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

(-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.
if the signs are the same you must add its opposite.
They become positive integers for instance - - 2 = 2
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
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.
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
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.
