== Code ==

=== In the Stage ===
The code in the [[Stage]] is the following:

<scratchblocks>
when green flag clicked
set [Current Equation: v] to ()
set [Answers: v] to ()
show list [Equations: v]
show list [Key: v]
show variable [Answer: v]
show variable [Current Equation: v]
Key::custom
</scratchblocks>

<scratchblocks>
define Key
delete all of [Key: v]
add [Use "*" for multiplication.] to [Key: v]
add [Use "/" for division.] to [Key: v]
add [Use "-" for subtraction.] to [Key: v]
add [Use "+" for addition.] to [Key: v]
add [To easily get the percent of a number, put the percent without the percent sign,] to [Key: v]
add [then press the check mark, then put "% of", then press the check mark, and then put the number you want] to [Key: v]
add [the percent of.] to [Key: v]
add [do not use commas.] to [Key: v]
add [Remember that you will have to put in a number then press the check mark then] to [Key: v]
add [put a symbol then press the check mark and then put a number.] to [Key: v]
add [You can use decimals as one number. Here is an example of a equation with a] to [Key: v]
add [number that has a decimal: 5395.58320349 (clicks the check mark) *] to [Key: v]
add [(clicks the check mark) 69483 (clicks the check mark) then you will receive the] to [Key: v]
add [answer to the equation, the answer to that one is 374901307.7] to [Key: v]
add [You can only make equations that are 3 clicks of the check mark.] to [Key: v]
add [So, if your equation is longer then just break down the equation into] to [Key: v]
add [smaller sections.] to [Key: v]
add ["square root of" will calculate the square root of a number.] to [Key: v]
add ["sin of" will calculate the sin of a number.] to [Key: v]
add ["cos of" will calculate the cos of a number.] to [Key: v]
add ["tan of" will calculate the tan of a number.] to [Key: v]
add ["asin of" will calculate the asin of a number.] to [Key: v]
add ["acos of" will calculate the acos of a number.] to [Key: v]
add ["atan of" will calculate the atan of a number.] to [Key: v]
add ["abs of" will calculate the abs of a number.] to [Key: v]
add ["floor of" will calculate the floor of a number.] to [Key: v]
add ["ceiling of" will calculate the ceiling of a number.] to [Key: v]
add ["ln of" will calculate the ln of a number.] to [Key: v]
add ["log of" will calculate the log of a number.] to [Key: v]
add ["mod" will calculate the mod.] to [Key: v]
add ["round" will round a number to a whole number.] to [Key: v]
</scratchblocks>

The key could be put in the [[Instructions]] page of the project instead, if it is going to be shared.

=== In the Sprite ===
After the code contained in the stage, the next part of the code will be part of a [[Sprite]]. Once the sprite is made, then the code is as follows:

<scratchblocks>
when green flag clicked
go to x: [0] y: [-140]
set drag mode [not draggable v]
show
delete all of [Calculating v]
delete all of [Making the Equation v]
</scratchblocks>

==== Set Pi and Euler's number ====

<scratchblocks>
when green flag clicked
set [Pi v] to [3.14159265358979323846264338327950288419716939937510] // This is Pi.
set [Number: e v] to [2.71828182845904523536028747135266249775724709369995] // This is Euler's number.
