Algebra is the study of unknown numbers.
With basic arithmetic, individual numbers are added, subtracted, multiplied, divided, and raised to powers or other basic functions. With algebra, however, we start looking at what happens when we compare numbers even though we do not know what specific values they have yet.
Some examples of standard equations from basic arithmetic are:

- $1+2=3$
- $2+3=5$
- $3\times3=9$
- $21+23=44$
- $7+8=15$
- $9-8=1$
- ${8\over4}=2$
- $ {2^3} = 8$

- $a+b=c$
- $2x+3y=z$
- $ax^2+bx+c=0$
- $(x+y)n=z$
- $a^2+b^2=c^2$
- $e=mc^2$
- $a^z+b^z=c^z | z<=2$
