In this one, you need to do more than adding alone. Place all the numbers 1 through 9 in the boxes so that each total shown across and down is correct. |
Below you see equations in which each of the numbers 9 through 0 are used once. The objective is to fill in the equations correctly. The gate symbol (#) stands for an odd number. With a little calculation and some perseverance you will find the answers...
| #4# | x | #8 | = | 26##0 | ||
| ### | x | 46 | = | #28#0 | ||
| #0## | - | 246 | = | #8# | ||
| ###6 | + | 8# | = | 204# | ||
| #4# | + | #8 | - | 206 | = | ## |
| 6## | + | 4# | - | ##0 | = | 28 |
| #6 | + | ## | + | 840 | = | #2# |
| #8 | + | 4# | + | 2## | = | 360 |
| 140 - 2 - 3 - 5 - 6 - 7 - 8 - 9 = 100 | With this puzzle you need to use all numbers 0 to 9 once and get 100 as result. Opposite you see an example. Can you find more? |
| 8 + (3+3) + (3* .3) = 24 | With this puzzle you need to use the numbers 3,3,8,8 only once and get 24 as result. Opposite you see an example in which the rules weren't followed. Can you do it correctly? |
| [ ] * [ ] = [ ][ ] [ ][ ] * [ ]=[ ][ ] |
Using all{1,2,3,4,5,6,7,8,9}, complete the following equations. How many solutions can you find? |
