Sorry for the typo in the last line. The required result of 15 + -10 = 5
What is 15 + -10 equal to?
15 + - 10 = 5 Answer.
If you're confused because of the signs then all you have to do is keep these pointers in mind:
Addition / Subtraction:
- 2 same signs result in addition i.e. - - = + , + + = + .
- 2 different signs result in subtraction i.e. - + = -, + - = - , sign of the bigger number is taken.
Division / Multiplication:
- When signs are different the minus sign is taken i.e. -*+ = -, -*+=-.
- When signs are same the plus sign is taken i.e. +*+=+, -*-=+.
to tihink of it simply, lets say you have 15 dollars, but you owe your friend 10 dollars, how much would you have left?
5! this is the same thing 15-10= 5
15 + -10 switch the + to a - because of the negative
5 is your answer
