Addition
Line up the columns and watch every carry fly into place.
Subtraction

Multiplication
See the area model split your problem into easy pieces.

๐ Fractions
Adding Fractions
Watch the bars get re-sliced into matching pieces, then joined together.
Subtracting Fractions
Take slices away โ and on hard mode, borrow a whole and watch it split.
Multiplying Fractions
Shade a square both ways โ the overlap IS the answer.
Dividing Fractions
See how many pieces fit, then see why flip-and-multiply gives the same answer.
๐ Decimals
Adding Decimals
Line up the points, pad the zeros, and watch carries cross the decimal point.
Subtracting Decimals
Borrowing works straight across the point โ see it happen digit by digit.
Multiplying Decimals
Count the places, multiply like whole numbers, then watch the point hop home.
Dividing Decimals
Slide the divisor's point until it's whole โ the answer never changes.
More foundation topics โ negatives, percents, order of operations โ are on the way. Miss a question and the animation replays your exact numbers โ pause it, step through it, watch it again.
