Solve is a calculator like no other!

Solve solves expressions as you type and features an innovative memory system to store and recall answers. Simply touch the answer to store it and touch the stored answer to use it in an expression. Solve has four tabs that select four different calculators each with its own color. Multiply numbers, calculate a tip and find a square root all without clearing your results!

Upgrade to Solve Pro and plot graphs with a single touch! Solve Pro is available in Solve as an in-app purchase.

Solve Pro (*requires in-app purchase) plots 2D and 3D functions using the x, y and θ variables. When you use the x, y and θ variables in an equation the answer will say Touch to Plot. Touch this label to graph the equation.

Plot 2D functions using the x variable. For example, "y=sin(x)" is just entered as "sin(x)".
• cos(x)
• abs(x)
• x^2+2x+6

Plot polar equations using the θ variable. For example, "r=2θ" is just entered as "2θ".
• 2θ
• sin(2θ)

Plot 3D functions by using the x and y variables. For example, "z=x+y" is just entered as "x+y".
• cos(x)+sin(y)
• x^2+y^2

Graph multiple functions by separating each equation with a comma.
• sin(x),cos(x)
• x,x^2,x^3

The T variable is used to create animated or time plots.
• cos(x+T)
• sin(x+T)*x
• cos(x+T)+sin(y+T)
