Explanation:

Before we start solving, we have to keep in mind that calculations are done from left to right and top to bottom. Let us begin solving:

Taking up the first row of the crossword puzzle, we figure the missing numbers between 1 to 9 that when multiplied and subtracted gives us 70. So, we try all multiplication combinations while skipping repetitive products. While doing so, we get 8 x 9 = 72.

Using logic, we can figure that if we subtract 2 from 72, we shall get 70. So, here we may have figured out the possible numbers in the top row.

However, is it 8 x 9 – 2 or 9 x 8 – 2 can only be figured after we solve the first column top to bottom.

Here, we have two possibilities figured out in the top left empty square which could either be an 8 or 9. So, we try different combinations and see that only 9 divided by 3 multiplied by 1 can give us 3 as in the puzzle.

Now, our math crossword puzzle looks like this:

Now, moving forward, we got four empty squares and four numbers left (4, 5, 6, 7).

Now, we solve the second column wherein we already have an 8 vertically and a 3 horizontally. So, we try several combinations and figure that 8 divided by 4 multiplied by 7 will get us 14 as in the puzzle.

Now, our math crossword puzzle looks like this:

Now, we solve the third column which should be easy as we have figured out more than 80 per cent of the puzzle, We got two numbers left now: 5 and 6. So, we have already figured a 2 vertically. So, 2 multiplied by 6 minus 5 will get us 7 as in the puzzle. Also, we see that all numbers satisfy the equations horizontally as well.

Horizontal Equations:

=> 9 x 8 – 2 = 70

=> 3 + 4 + 6 = 13

=> 1 + 7 x 5 = 40

Vertical Equations

=> 9  3 x 1 = 3

=> 8  4 x 7 = 14

=> 2 x 6 – 5 = 7

Now, our math crossword puzzle looks like this:
