A quick digit puzzle for fifth grade.

Between twenty and thirty, I am even, and my digits add up to five.

Pistas

None of these sums equal 5, so there is no number that fits all conditions.

Compute the sum of digits: 2+0=2, 2+2=4, 2+4=6, 2+6=8, 2+8=10.

Consider every even number in the 20s: 20, 22, 24, 26, 28.

7 + 8 = ? Choose the number word.

It’s a teen number.

3

4

Pistas

5

7 + 5 = ? Write the word
