If you want to turn right 10 degrees, for example, you would write:If you want to change a variable or do some math, Web Turtle supports a very simple math syntax:

`RIGHT 10`

If you want to turn right "A" degrees - that is, "the number that's stored in 'A'" degrees, you would write:

`RIGHT A`

To put a number "into" the variable "A", you use the

`LET`

command:

`LET A 10`

Since "10" is a number, we can replace it with another variable:

`LET A B`

(This copies the number that's in "B" right now into variable "A.")

`LET A 1+1`

Puts the value of (1+1), or 2, into "A."

`LET A B+1`

Puts the value of (B+1) into "A."

`LET A A+1`

Puts the value of (A+1) into "A," thus incrementing A by 1.

`LET A 10-5`

Puts the value of (10-5), or 5, into "A."

`LET A 15/5`

Puts the value of (15/5), or 3, into "A."

`LET A 12/5`

Puts thewholevalue of (12/5) — the whole part of 2.4, or 2 — into "A."

Note:Web Turtle currently only deals with 'integer' numbers (or 'whole' numbers).

`LET A 12%5`

Puts the remainder of (12/5), or 2, into "A."

`LET A 1?10`

Picks a random number between 1 and 10, and puts it into "A."

`LET A 10/2-1`

Puts the value of (10/(2-1)), or 10, into "A." Note, this example shows that Web Turtle hasno operator presidence! All operations occur from right to left!
