DAY 363:

Today’s Challenge

. . . is is a 5puzzle-related question, similar to our board game of the same name.

Your task is to make the target number of 15 by adding together five numbers. You are limited to using 1 to 5, but these can be used any number of times in each calculation.

One such way of making 15 is 3+3+3+3+3.  How many other ways can you find?

The 7puzzle Challenge

The playing board of the 7puzzle game is a 7-by-7 grid containing 49 different numbers, ranging from 2 up to 84.

The 6th column of the playing board contains the following seven numbers:

7       30       36       40       49       54       64

Using these seven numbers exactly once each, with + – × ÷ available to use in your calculation, can you arrive at the target number of 100?

Make 363 Challenge
