Solve the Expression: Finding the Missing Digit in 69+0?70-0

To solve this mathematical problem, we need to compare two expressions: $69 + 0$ and $70 - 0$.

We'll follow these steps:

• Calculate $69 + 0$.
• Calculate $70 - 0$.
• Compare the resulting values.

Let's break it down:

Step 1: Calculate $69 + 0$.

We use the identity property: adding zero to a number does not change its value. Therefore, $69 + 0 = 69$.

Step 2: Calculate $70 - 0$.

Similarly, subtracting zero from a number does not change its value. Therefore, $70 - 0 = 70$.

Step 3: Compare the two results.

We have $69$ from the first expression and $70$ from the second. Clearly, $69$ is less than $70$.

Therefore, the answer is $69 + 0 < 70 - 0$, represented as: $<$.
