On the first day of school, Ava sees that her friends Cole and Xavier have both grown a lot over the summer. Xavier was 4 feet tall and grew 3 inches. Cole was 50 inches tall and grew 2 inches over the summer. What is the difference between Cole and Xavier’s height now?
First, we need to be sure we are comparing the same units, so let's convert feet into inches. There are 12 inches in 1 foot. So Xavier was 12 x 4 =

<output>48</output>
48 inches tall.
Xavier grew to be 48 + 3 = 
<gadget id="calculator">48+3</gadget>
<output>51</output>
51 inches.
Cole grew to be 50 + 2 = 
<gadget id="calculator">50+2</gadget>
<output>52</output>
52 inches.
The difference between Cole and Xavier's height is now 52 - 51 = 
<gadget id="calculator">52-51</gadget>
<output>1</output>
1 inch.
