DAY 348:

Today’s Challenge

. . . is a number puzzle with the same concept as my FlagMath series of card games. Here is an example of a typical challenge in the Multiplication edition.

Each of the nine letters, A-I, in the two sections below contains a multiplication calculation:

  • Section 1

E:9×4   H:6×5   G:8×2   A:6×4   D:10×2   I:4×3   F:5×2   B:8×3   C:7×5

  • Section 2

F:6×6   I:9×3   A:5×3   H:4×4   C:3×3   E:8×2   B:7×4   D:5×4   G:10×3

Which is the only letter to have the SAME answer in BOTH sections?

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 2nd & 3rd columns of the playing board contain the following fourteen numbers:

2    4    10    12    15    16    17    33    35    45    48    70    80    81

Find the square root of each of the square numbers listed above. What is their sum?

Make 348 Challenge

Can you arrive at 348 by inserting 2, 3, 4, 5 and 6 into the gaps on both lines below?

  •  (◯²+◯²)×(◯²÷◯+◯) = 348
  •  (×◯+◯)×ײ = 348

Answers can be found here.
