that means that

a = 1

b = 0

c = 2

d = 1

e = 3

i'm pretty sure i did something wrong... i'm not that good at math anyway

what i mean is that you type something like $x=1$ to define a variable called "x". then typing in $x+x$ would return 2. there should also be a command to delete all the variables (for example, $\text{deleteVariables}$.)
