This is an addition problem because we have the difference in height from the question. The lamp is \(\displaystyle 23\) centimeters tall and wall is \(\displaystyle 58\) centimeters taller than the lamp, \(\displaystyle 58\) is our difference. We can add our difference to the lamp's height to find out how tall the wall is. 

\(\displaystyle \frac{\begin{array}[b]{r}23\\ +\ 58\end{array}}{ \ \ \ \space 81}\)

This is an addition problem because we have the difference in length from the question. The pillow is \(\displaystyle 74\) centimeters long and couch is \(\displaystyle 26\) centimeters longer than the pillow, \(\displaystyle 26\) is our difference. We can add our difference to the pillow's length to find out how long the couch is. 

\(\displaystyle \frac{\begin{array}[b]{r}74\\ +\ 26\end{array}}{ \ \ \ \space 100}\)

This is an addition problem because we have the difference in height from the question. The grill is \(\displaystyle 61\) centimeters tall and fence is \(\displaystyle 38\) centimeters taller than the grill, \(\displaystyle 38\) is our difference. We can add our difference to the grill's height to find out how tall the fence is. 

\(\displaystyle \frac{\begin{array}[b]{r}61\\ +\ 38\end{array}}{ \ \ \ \space 99}\)

This is an addition problem because we have the difference in height from the question. Alison is \(\displaystyle 52\) centimeters tall and David is \(\displaystyle 39\) centimeters taller than her, \(\displaystyle 39\) is our difference. We can add our difference to Alison's height to find out how tall David is. 

\(\displaystyle \frac{\begin{array}[b]{r}52\\ +\ 39\end{array}}{ \ \ \ \space 91}\)

This is an addition problem because we have the difference in length from the question. The rug is \(\displaystyle 56\) centimeters long and room is \(\displaystyle 42\) centimeters longer than the rug, \(\displaystyle 42\) is our difference. We can add our difference to the rug's length to find out how long the room is. 

\(\displaystyle \frac{\begin{array}[b]{r}56\\ +\ 42\end{array}}{ \ \ \ \space 98}\)

This is an addition problem because we have the difference in length from the question. The table is \(\displaystyle 54\) centimeters long and room is \(\displaystyle 39\) centimeters longer than the table, \(\displaystyle 39\) is our difference. We can add our difference to the table's length to find out how long the room is. 

\(\displaystyle \frac{\begin{array}[b]{r}54\\ +\ 39\end{array}}{ \ \ \ \space 93}\)

This is a subtraction problem because we want to know how much longer the plate is compared to the bowl, or the difference in their length. 

\(\displaystyle \frac{\begin{array}[b]{r}41\\ -\ 17\end{array}}{ \ \ \ \space 24}\)

This is a subtraction problem because we want to know how much taller the tree is compared to the swing set, or the difference in their height. 

\(\displaystyle \frac{\begin{array}[b]{r}100\\ -\ 76\end{array}}{ \ \ \ \space 24}\)

This is a subtraction problem because we want to know how much longer the TV is compared to the remote, or the difference in their length. 

\(\displaystyle \frac{\begin{array}[b]{r}90\\ -\ 42\end{array}}{ \ \ \ \space 48}\)

This is a subtraction problem because we want to know how much longer the dog's body is compared to his tail, or the difference in their length. 

\(\displaystyle \frac{\begin{array}[b]{r}85\\ -\ 62\end{array}}{ \ \ \ \space 23}\)
