When the replacement fields and arguments are in the same order, the 
indexes are optional. The following works, and might be less confusing.

formatStr = 'Integer {}, {}, {}, and the sum is {}.'

We no longer have a space shortage ;-). The following is easier to read.

equations = formatStr.format(x, y, z, x+y+z)

Compute quotient and remainder with the divmod function.

q, r = divmod(x, y)

Both are computed at once and x // y and x % y just toss the other 
answer. x // y == divmod(x, y)[0], x % y == divmod(x, y)[1]
