Let's solve

Tap to subtract {{prob.t2}} Tens and {{prob.o2}} Ones

Tens removed: {{s1.removedT}} / {{prob.t2}}

Ones removed: {{s1.removedO}} / {{prob.o2}}

Drag to set up

Place the digits to set up the math

{{d.val}}

{{ s2.targets[0].filledId ? s2.targets[0].expected : '' }}

{{ s2.targets[1].filledId ? s2.targets[1].expected : '' }}

-

{{ s2.targets[2].filledId ? s2.targets[2].expected : '' }}

{{ s2.targets[3].filledId ? s2.targets[3].expected : '' }}

{{ step === 3 ? 'Solve the Ones' : 'Solve the Tens' }}

Drag the answer to the highlighted box

{{prob.t1}}

{{prob.o1}}

-

{{prob.t2}}

{{prob.o2}}

{{ (step > 4 || s4.ansPlaced) ? prob.ansT : '' }}

{{ (step > 3 || s3.ansPlaced) ? prob.ansO : '' }}

Drag to plate
