Here is a bit tricky puzzle that is 6 years or upper juniors (9/11). Ideal for wet breaks!
Use only the digits 1 through 9 complete correct the number of sentences, both horizontally and vertically, so they all are.
A good knowledge of tables is needed, along with the ability to add and subtract mentally.
The hardest part of this puzzle is getting started and the best approach is to use process and improvement by picking one row or column that can have only a limited number of opportunities. This wouldn't be the first row or column down.
This particular puzzle to look at the first row is a x b – c = 34. Start by watching combinations of numbers that when multiplied, more than 34 (but no more than 43 if the maximum subtraction is 9) and then see what number can be subtracted to leave 34.
An important note about this: all calculations are done in the following order: Bodmas is not applicable.
1-9 (1A)
