Red Envelope Math

It's the Lunar New Year, and Zip is in charge of the red envelopes. Grandma, Grandpa, the aunties and uncles all hand over lucky money, and every envelope has to be fair. Ten questions: equal shares, leftovers, pooled gifts, shares by parts, two envelopes to even out. All amounts are made up.

How to play

Read the story. Who's giving, how much, and for how many children. The coin badge shows the total.
Pick the fair answer. Four answers, one right. Tap it or press 1 to 4. Every answer shows the working, so you learn the method.
Three lives. A wrong answer costs a life. Ten envelopes, getting harder: leftovers, family rules, working backwards.
Score. 100 per right answer, plus 20 for each one in a row before it (up to +80). A perfect run is 1,600.

Quick tips

Check with multiplication. If 4 envelopes hold 22 each, 4 × 22 should give back the total of 88.
Add before you share. When two people give, pool the money first, then divide once.
