int a = 22;
int b = a;
int c = b + 1;
int d = 1, e;

int a = 22;
int b = a;
int c = b + 2;
int d = 2, e;

int a,b,c;

int a,b,c = 1;

Declare var before using it

Arithmetic Instructions

a+b
Operand 1

Operand 2

Operator

NOTE - single variable on the LHS

Arithmetic Instructions
VALID
a=b+c

INVALID
b+c=a

a=b*c

a = bc

a=b/c

a = b^c

NOTE - pow(x,y) for x to the power y
