Math

"Now it's time for everybody's favorite subject: Math!"

- Baldi

Math is a subject in the Baldi's Basics series.

Description
The subject consists of random arithmetic problems with addition, subtraction, multiplication, and division of whole numbers, with one, two, or rarely, three digits. The numbers for Baldi's Math Machine and the You Can Think Pad range from 0 to 9, and they only use addition and subtraction. In the current camping field trip in Hide-and-Seek and Explorer Mode, the numbers range from 0 to 60 and it introduces multiplication. In the Field Trips mode, there are 3-digit numbers and it is the only mode where division is featured.

Usage
Baldi's Math Machine is found randomly in classrooms to solve one-digit math questions of addition or subtraction. There are number balloons which the player needs to insert into the Math Machine to answer the question.

In the camping field trip since V0.3, there are also two-digit numbers. The questions are displayed in logs, and the answers are displayed in campfires that the player can swap. The logs must drop down into the correct campfires based on the questions and answers. After completing five sets of campfires, multiplication problems are introduced.

In the Field Trips mode, division problems are added when there are four campfires.

Math is firstly used in the You Can Think Pad. They are solved by typing the numbers on the keyboard or touching/clicking the number buttons on the number pad. When solving math questions for the second time and onward, the third question will end up being corrupted and impossible to answer correctly, being cluttered with overlaid numbers and symbols.

Trivia

 * Math is the first and only featured subject used for all games as of now.
 * Even though there are no multiplication problems in the You Can Think Pad, Baldi briefly uses multiplication in the impossible question.
 * Baldi has an unused audio clip which gives a division problem in the You Can Think Pad. It goes unused due to being impossible to solve when Baldi gives a division question like $$1$$ ÷ $$0$$, $$2$$ ÷ $$3$$, and so on.
 * The range of the possible correct answers for the You Can Think Pad 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, with $$9 + 9 = 18$$ being the highest value and $$0 - 9 = -9$$ being the lowest.
 * However, in Baldi's Math Machine, the range is {$$a$$ ∈ ℤ, $$0$$ ≤ $$a$$ ≤ $$9$$} to only allow 0 or positive single digit answers. It also applies to the camping field trip, except that the positive answers can go up to 3 digits.
 * Although -0 is technically a correct answer for questions like $$2 - 2$$, the You Can Think Pad still counts it as incorrect.
