Solve the Equation: Finding Missing Number in 87 + □ = 92

Solve the following equation,

using two jumps on the number line below:

$87+\Box=92$

To solve the problem of $87 + \Box = 92$ by using two jumps on the number line, we begin by identifying and making our jumps:

• First jump: Move from 87 to the nearest round number, which is 90. This jump is of size $90 - 87 = 3$.
• Second jump: Now move from 90 to 92. This jump is of size $92 - 90 = 2$.

Add the two jumps together:
First jump: 3
Second jump: 2
Total jump: $3 + 2 = 5$

Therefore, the value of the box ($\Box$) that satisfies the equation $87 + \Box = 92$ is $\Box = 5$ .
