Line 1:
Line 1: − The Forth programming language uses a stack for computations.+ − On the right of the screen, the Forth words + - x / DUP and SWAP are implemented with blocks.+ − On the left, a Forth like program to compute 3^2 +4^2 = 25+ − − − − − [[File:Turtle Art Activity forth.ta]] − − What computations can you make with this set of words? − − Make additional words with Turtle blocks − − The - and / words process the operands on the stack in the reverse order to Forth, you can fix the word definitions on the right with SWAP
