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.
