1. $14 + 10 + 6 = 40 - \underline{\quad}$

$14 + 10 + 6 = \underline{\quad}$
$30 = 40 - \underline{\quad}$
so, $14 + 10 + 6 = 40 - \underline{\quad}$

Explanation:

Step1: Calculate left-hand side sum

$14 + 10 + 6 = 30$

Step2: Solve for unknown value

Let the unknown be $x$. We have $30 = 40 - x$, so $x = 40 - 30 = 10$

Answer:

$14 + 10 + 6 = 30$
$30 = 40 - 10$
So, $14 + 10 + 6 = 40 - 10$
The missing number is 10
