Book Free DemoSimilar to addition, we can subtract algebraic expressions by adding the coefficient of like terms together. i.e. variable coefficient with its similar variable coefficient and constant with constant except that the fact we will include the term additive inverse.
Example:
To subtract from , we have to add the additive inverse of with .
Additive inverse of is \(=\)
Therefore,
Important!
- Subtracting \(2x\) is the same as adding \(-2x\) and subtracting \(-11a\) is same as adding \(11a\).
- \(x\) is the additive inverse of \(-x\) and they are equal in numeric value with opposite sign.
