So we
can deal with X  4, and 3X, and stuff like that, right?






What

you were learning about multiplying numbers together, 


maybe you
learned about exponents. 


Exponents
are little numbers that say 


"Multiply
this thing to my left times ITSELF this many times." 





So: 








These
little exponent numbers are just a way 


to write
stuff in less space. 





MATH TYPES
JUST LOVE TO SAVE SPACE!






SO how do
we save space writing ... 





X times X






We write
it like this ... 





X^{2}
