    Are you trying to perform some multiplications in the nested for loops and assign the values to a and y?

    Check out the values generated here:

    #!/bin/bash

for i in {1..7}; do
    for j in {1..5}; do
        a=$(( $i*630 ))
        y=$(( $j*900 ))
        echo "a: " $a "y: " $y
    done
done
