Complete the Expression: Finding the Missing Operator in 30+4□63-30

To solve this problem, we will follow these steps:

• Simplify each side of the expression separately.
• Compare the resulting values to determine the correct inequality sign.

Step 1: Simplify the left side of the expression.
Calculate $30 + 4$, which equals $34$.

Step 2: Simplify the right side of the expression.
Calculate $63 - 30$, which gives us $33$.

Step 3: Compare the simplified results.
We have $34$ on the left side and $33$ on the right side. Clearly, $34$ is greater than $33$.

Thus, the correct inequality sign to substitute for the box is $>$.
