Solve It! Pre-Algebra
Negatives, ratios, equations
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Solve It! teaches pre-algebra, the math that comes before Algebra 1, one idea at a time, with animated pictures that show why each rule works: why two negatives make a positive, why you flip and multiply, why the same move keeps a balance level. When a skill clicks, the Play tab turns it into a quick game.
LEARN
• 14 tracks and 66 short lessons on five paths. Numbers: Negative numbers, Fractions and decimals, Exponents and roots, Scientific notation, Real numbers. Proportion: Ratios and rates, Percent. Algebra: Expressions, Equations, Systems of equations. Graphs: Lines and slope, Functions. Geometry: Pythagorean theorem, Volume
• Pictures for every idea: a thermometer, zero pairs, hops on a number line, x-bags, algebra tiles, an area model, a balance that makes the same move on both sides, ratio tables, double number lines, tape diagrams, percent bars, fraction bars, decimal grids, long division, square and cube stacks, slope steps on a grid, function machines, lines that cross, squares on a right triangle's sides, solids that fill up
• Every lesson goes learn, practice, quiz, with no timer or lives
• A wrong answer brings the picture back with a hint about that exact slip: adding the bottoms, flipping the wrong fraction, getting the sign wrong, reading a percent as dollars
• Tell it where you are and it suggests a first lesson. Nothing is locked behind progress

• Seven games: Integer blitz, Solve for x, Ratio tables, Percent of, Powers and roots, Find the slope, Right triangles
• Pick the operations for Integer blitz, and one-step, two-step, negative or x-on-both-sides equations for Solve for x
• Beat the clock for 1, 2 or 3 minutes with 3 lives, or get 20, 40 or 60 in a row on a stopwatch
• Four answer choices, a ready-set-go countdown, and a cheer at streaks of 5, 10 and 20

Ratings & Reviews
• Ready for iPhone Duo: on the outer screen the tabs and buttons move to the side, the inner screen gets bigger pictures and buttons, and a lesson keeps its place when you fold or unfold, with its picture and answers on either side of the fold.
• A long equation in a game always fits its card.
• Small fixes.
