$$\begin{array}{|l|l|l|l|} \\hline 1+14= & 16-5= & 19-5= & 15-13= \\\\ \\hline 20-14= & 3+9= & 7+5= & 7+2= \\\\ \\hline \\end{array}$$

\\

Explanation:

Calculate the first row of equations

We solve each addition and subtraction expression in the first row.

• For \(1 + 14\):

$$ 1 + 14 = 15 $$

• For \(16 - 5\):

$$ 16 - 5 = 11 $$

• For \(19 - 5\):

$$ 19 - 5 = 14 $$

• For \(15 - 13\):

$$ 15 - 13 = 2 $$

Calculate the second row of equations

We solve each addition and subtraction expression in the second row.

• For \(20 - 14\):

$$ 20 - 14 = 6 $$

• For \(3 + 9\):

$$ 3 + 9 = 12 $$

• For \(7 + 5\):

$$ 7 + 5 = 12 $$

• For \(7 + 2\):

$$ 7 + 2 = 9 $$

Answer:

\(1 + 14 = 15\)	\(16 - 5 = 11\)	\(19 - 5 = 14\)	\(15 - 13 = 2\)
