Solving math problems using the You Can Think Pad.

Math is a subject for the You Can Think Pad in Baldi's Basics Classic or the Math Machine in Baldi's Basics Plus.

Description

The subject has a simple, 1st grade-based difficulty, mostly with addition and subtraction of whole numbers, and only one digit. The numbers randomly range from 0 to 9.

Usage

Math machine screenshot

A math problem in the Math Machine.

Randomly in Classrooms, there are Math Machines to solve math questions. There are Number Balloons which the Player needs to insert into the machine to answer the question.

In Baldi's Basics Classic and Baldi's Basics Birthday Bash, math is firstly used for the You Can Think Pad. They are solved typing the numbers on keyboards or touching those numbers buttons on number pad. When solving math questions for the second time and onward, the third question will end up being corrupted and impossible to correctly answer, cluttered with overlaid numbers and symbols.

Trivia

  • Math is the very first featured subject and the only subject used for Baldi's Basics Classic.
    • Even though there are no multiplication problems, Baldi briefly uses multiplication in the glitched question.
    • Baldi has an unused audio clip which gives a division problem. It goes unused due to being impossible to solve when Baldi gives a question like 1 divided by 0 and so on.
  • The range of the possible correct answers is {$ a ∈ ℤ, -9 ≤ a ≤ 18 $}, where $ a $ is the value of the answer. The reasoning behind this is the fact that both the first and second number can only be integers from 0 to 9; $ 9 + 9 = 18 $, however $ 0 - 9 = -9 $.
    • However, in the Math Machine, the range is {$ a ∈ ℤ, 0 ≤ a ≤ 9 $} to match the amount of Number Balloons.
  • Although, -0 is technically the correct for questions like 2 - 2, the You Can Think Pad still counts it as incorrect.
