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

Emojicode supports arithmetic operators for:

  • ➕: addition
  • ➖: subtraction
  • ✖️: multiplication
  • ➗: division
  • 🚮: modulo (divides and gives the remainder)

For example:

4 ➕ 2 ➡️ score1     💭 scores1 is 6

4 ➖ 2 ➡️ score2     💭 scores2 is 2

4 ✖️ 2 ➡️ score3     💭 scores3 is 8

4 ➗ 2 ➡️ score4     💭 scores4 is 2

4 🚮 2 ➡️ score5     💭 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 x’s in the emoji picker. Make sure to use ✖️.

2.

Use string interpolation to print a message that says:

The tip is $[tip]

Where [tip] is the value of the tip constant.
