The part that matters

Different questions every time.

A question with only the numbers swapped can be answered by copying the steps from the last one. Tuterly keeps the same concepts and changes at least two other things: the context, the structure, the layout, the type of numbers, or how it’s shown. Here is the example from the rules its question writer follows.

The question they got wrong

Solve for $x$ :

$\frac{x+2}{3} = \frac{2x-1}{5}$

Show solution

Multiply both sides by 15 (the lowest common denominator):

5(x+2) = 3(2x-1)

5x + 10 = 6x - 3 \quad\Rightarrow\quad x = 13

Check: $\tfrac{15}{3} = 5$ and $\tfrac{25}{5} = 5$ .

Not this: only the numbers changed

Solve for $x$ :

$\frac{x+4}{3} = \frac{2x-3}{5}$

This: new context and layout, same concepts

Mia’s phone plan costs a third of $(c + 6)$ dollars a week. Leo’s costs a quarter of $(3c - 2)$ dollars. For what value of $c$ do they pay the same?

Show solution

\frac{c+6}{3} = \frac{3c-2}{4}

Multiply both sides by 12:

4(c+6) = 3(3c-2)

4c + 24 = 9c - 6 \quad\Rightarrow\quad c = 6

Both pay $4 a week.

Or this: new structure, same concepts

Sam solved this equation and got $x = 1$ .

$\frac{x+1}{2} = \frac{x-3}{4}$

Find his mistake and give the correct answer.

Show solution

Multiply both sides by 4:

2(x+1) = x - 3

2x + 2 = x - 3 \quad\Rightarrow\quad x = -5

Sam’s $x = 1$ comes from writing $x + 3$ instead of $x - 3$ on the right.

Why it helps

Small details that make it stick.

Hints, not answers

Stuck? A hint shows the method, then the first step. Never the answer.

Explain this

Got it wrong? It points to the exact step that went wrong.

Reads handwriting

If a photo is unclear it asks “Is this what you wrote?”, or they can type it.

Questions

Good to know.

Isn’t this just a way to get answers?

No. The solution is hidden until they choose to see it, hints never give the answer away, and a question is only mastered when they get fresh versions right themselves.

What if there are several questions in one photo?

Tuterly splits them into a checklist, so they can choose which ones to add.
