The image contains a set of number puzzles where "A" and "B" are placeholders that need to be replaced with the correct values. The instruction is to calculate and fill in the values of "A" and "B" in each of the 5 grids provided.

Let’s break down each puzzle systematically:

Puzzle 1:

The grid pattern seems to follow a simple arithmetic logic:

Looking at the rows and columns, it's possible that either sums or some pattern like multiplication/division between values is being applied. We can check the values and identify patterns to solve for "A" and "B".

Puzzle 2:

Another grid pattern is given:

The calculations for this would likely involve looking for common patterns like sums, products, or differences between neighboring numbers.

Puzzle 3:

This seems to be a larger grid:

Once again, A and B can be found by applying appropriate arithmetic rules. They may be row-based, column-based, or diagonally based sums or products.

Puzzle 4:

Identifying patterns such as addition or multiplication sequences will reveal the values of A and B.

Puzzle 5:

The pattern in this grid seems more complex, possibly involving multiplication or factors.

I'll start with solving these puzzles by identifying the patterns systematically.
