You can add, subtract, multiply, and divide, here are some basic examples:

Here are some other shortcuts you can take:

in conditional statements, there are some other operators:

I think I covered all of the basics.

**Code:**```
```

Adding:

int a = 1;

int b = 2;

int c = a + b;

int d = b - a;

int e = b * a; //I'm no expert, but perhaps in calculator C there is a different function for this, as pointers may act weirdly?

int f = b / a;

Here are some other shortcuts you can take:

**Code:**```
```

int i = 0;

i++; //Increments i by 1

i--; //decrements i by 1

i += 2; // adds 2 to i

i -= 2; // subtracts 2 from i

i = 10; //sets i to 10

i *= 10; //multiplies i by 10

i /= 10; //divides i by 10

in conditional statements, there are some other operators:

**Code:**```
```

int foo = 1;

if (i == 10 || foo == 2) //if i is equivalent to 10 or foo is equal to two

{

foo = 1; //set foo to 1

}

if (i == 5 && foo == 1) //if i is equal to 10 and foo is equal to one

{

i = 0; // set i to 0

}

if (i == 5 %% foo != 1) //if i is equal to 10 and foo is NOT equal to one

{

foo = 10; // set foo to 10

}
