Solve the Equation: Finding the Missing Number in 82-□=78

Question

Solve the subtraction exercise,

using two jumps on the number line below:

$82-\Box=78$

To solve the subtraction $82 - \Box = 78$ using jumps on a number line, follow these steps:

Step 1: Start at the number 82 on the number line.
Step 2: Make the first small jump down to 80, the closest round number below 82.
Step 3: Calculate the size of this jump. The jump from 82 to 80 is 82 - 80 = 2.
Step 4: From 80, make a second jump down to 78.
Step 5: Calculate the size of this second jump. The jump from 80 to 78 is 80 - 78 = 2.
Step 6: Add the sizes of both jumps to determine the total subtracted value: 2 + 2 = 4.

Therefore, the value of $\Box$ in the subtraction problem $82 - \Box = 78$ is $4$ .
