Subtracting Subtraction, Part 1
Some things are easier than others. The elevator is easier than the stairs. Criticizing others’ ideas is easier than originating one’s own. Addition is easier than subtraction. Let’s focus on the last of these. Why is subtraction more difficult than addition? Borrowing. When a digit in the subtrahend (the second number) is greater than the […]

Rator Vaders: Week 3
This week I added strings, chars, and function and method calls to Rator Vaders. Now max(“abc”.indexOf(‘c’), (“a” + “b”).length()) can attack Earth! I also added a weighting system to the random expression generator to make it easy to progressively generate more complex expressions as the player advances in the game. Initially, only the arithmetic operators […]
Precedence vs. Evaluation Order
I’ve been working on a little computer science learning game called Rator Vaders. Complex expressions drop from the sky, and the player has to fire at the highest precedent operator and evaluate it. This process continues until only a literal value is left, which can be sent to the Big Bit Bucket in the Sky […]
