How MOD and ISEVEN and ISODD works

  • What does MOD do?

    MOD gives the remainder after dividing: =MOD(17,5) is 2, because 5 goes into 17 three times with 2 left over.

  • How do you spot even and odd numbers?

    A number is even when MOD(A2,2) is 0. ISEVEN and ISODD ask the same question and answer TRUE or FALSE: =ISEVEN(A2).

  • Where is MOD useful?

    Leftovers after making teams or packs, and the spare days after whole weeks: =MOD(B2,7).
