 “ Now it's time for everybody's favorite subject: Math! ” — Baldi

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

## Description

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

## Usage

The math is typically used for the You Can Think Pad. When solving math for the second time and onward, the third question will end up glitched and impossible to correctly answer it, cluttered with overlaid numbers and symbols.

Randomly in Classrooms, there are Math Machines to solve math questions. However, instead typing the numbers on keyboards or touching those numbers buttons on number pad, there are Number Balloons which the Player needs to bring them to answer the question.

## 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 which gives a division problem. It was 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.
