addition of real numbers

4 odd numbers and 2 even numbers have to equal an even number. Therefore, 4 odd and 2 even cannot equal 13 regardless of what the odd and even numbers are.

$2(1+2+3) = 12 \ne 13 \implies \boxed{\text{False}}$

1 + 2 + 3 + 1 + 2 + 3 = 12 not 13

Therefore, the answer is false.
