Arithmetic Operations

Computers are incredible at doing calculations. Now that we have declared variables, letโs use them with arithmetic operators to calculate things!

Emojicode supports arithmetic operators for:

`โ`

: addition`โ`

: subtraction`โ๏ธ`

: multiplication`โ`

: division`๐ฎ`

: modulo (divides and gives the remainder)

For example:

4 โ 2 โก๏ธ score1 ๐ญ scores1 is 6 4 โ 2 โก๏ธ score2 ๐ญ scores2 is 2 4 โ๏ธ 2 โก๏ธ score3 ๐ญ scores3 is 8 4 โ 2 โก๏ธ score4 ๐ญ scores4 is 2 4 ๐ฎ 2 โก๏ธ score5 ๐ญ scores5 is 0

Here, we are doing some arithmetic operations and storing the results in five different constants.

### Instructions

**1.**

In the code editor, we have already declared and initialized a variable called `amount`

.

Declare a new variable named `tip`

and give it the value of `amount`

multiplied by `0.2`

.

**Note:** There are quite a few variations of xโs in the emoji picker. Make sure to use `โ๏ธ`

.

**2.**

Use string interpolation to print a message that says:

The tip is $[tip]

Where `[tip]`

is the value of the `tip`

constant.
