Using Algebra – Collecting Terms

Achbar the Egyptian is having great difficulty counting his camels! Can you help him?

What about the Pyramids?

And the sphinx?

Exercise Simplify:

Is it possible for Achbar to add one camel to two pyramids? A camel and a pyramid are two totally different things, we cannot add them! Only terms are the same Let us collect them by adding

Exercise Simplify:

Subtract What about: Subtracting camels is just as easy as adding them! One camel, c not 1c, we do not need the 1

Subtract What about:

Exercise Simplify:

Subtracting Different Terms What about: Since a camel and a pyramid are different things, we cannot subtract them! Cannot simplify!

Subtracting Different Terms What about: Collect the pyramids first, then the camels.

Subtracting Different Terms What about: The negative sign relates to variable c

Exercise Simplify:
