Equation Balance Lab
Choose a side, then tap a tile to add it. The equation must be modeled correctly before solving.
Tap a tile to flip its sign. Tap ↻ on an x-tile to turn it sideways. Tiles begin ungrouped. When ready to divide, rotate each x-tile using ↻, then drag the unit tiles on the opposite side into equal groups yourself. Crossing the wall changes the sign.
Select an operation and apply it to BOTH sides. Individual flips are available, but changing one tile by itself breaks the balance.
Tap to flip signs. Tap ↻ to rotate x-tiles horizontally when you reach the division step. Then manually drag the constants opposite them into equal groups. The game does not organize them for you. In Cancel Zero Pair mode, tap two opposite tiles on the SAME side. Arrangement and rotation do not alter the equation.
