Here's the catch: a score today fades by next week unless you revisit it. Mochi schedules each idea to come back right before you'd forget, and turns keeping up into growing a pet.

The Pythagorean Theorem What is a right triangle?
A right triangle is a triangle that has one angle equal to exactly 90 degrees.
Prime Numbers What is a prime number?
A prime number is a whole number greater than 1 that has exactly two factors: 1 and itself.
Fractions What is a fraction?
A fraction represents a part of a whole, written as one number over another (e.g., 3/4).
Pi What is pi?
Pi (π) is the ratio of a circle's circumference to its diameter. This ratio is the same for every circle, regardless of size.
Probability Basics What is probability?
Probability is a number between 0 and 1 that measures how likely an event is to occur. A probability of 0 means impossible; 1 means certain.
Exponents and Powers What is an exponent?
An exponent tells you how many times to multiply a base number by itself. For example, in 3^4, the exponent is 4.
Functions What is a mathematical function?
A function is a rule that assigns exactly one output value to each input value. The input is called the argument and the output is the function's value.
Triangles What is a triangle?
A triangle is a polygon with exactly three sides and three angles. The word comes from the Latin 'triangulus,' meaning three-cornered.
Linear Equations What is a linear equation?
A linear equation is an algebraic equation where each term has an exponent of at most 1, producing a straight-line graph when plotted.
Logarithms What is a logarithm?
A logarithm answers the question: to what exponent must a base be raised to produce a given number? For example, log base 2 of 8 equals 3 because 2³ = 8.
