DAY 362:

Today’s Challenge

. . . is a number puzzle similar to my MATHELONA series of challenges, but much more difficult.  If you enjoy this, feel free to click the above link to place an order for my pocket book of number puzzles.

Your task is to fill all 24 gaps below with the numbers 1-24.  Each number should appear once each and ALL eight lines/equations must work out arithmetically.

◯   +   ◯   =   ◯
◯   +   ◯   =   ◯
◯   +   ◯   =   ◯
◯   +   ◯   =   ◯
◯   +   ◯   =   ◯
◯   +   ◯   =   ◯
◯   +   ◯   =   ◯
◯   +   ◯   =   ◯

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 5th column of the playing board contains the following seven numbers:

8       11       14       18       25       44       84

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

Make 362 Challenge

Can you arrive at 362 by inserting 4, 9, 16, 25 and 36 into the gaps below?

◯×(+√◯–√◯)+√◯ = 362
