Solve Subtraction Pattern: From 70-40=30 to 70-41

To solve this problem of basic subtraction, follow these steps:

• Step 1: Identify the numbers involved in the subtraction. In this case, $70$ is the minuend and $41$ is the subtrahend.
• Step 2: Apply the subtraction formula: $a - b = c$.
• Step 3: Perform the subtraction $70 - 41$.

Let's perform the subtraction:
Start by subtracting the units: 0 - 1. Since 0 is less than 1, we need to borrow 1 from the tens place:
This changes 70 to 60 (since we are borrowing 10 to get 10 in the units place), and then subtract 10 - 1 = 9 in the units place.
Now, in the tens place, we subtract 6 - 4 = 2 (since we borrowed 1 from the 7 to make it 6).

Bringing it all together, the result of $70 - 41$ is $29$.

Therefore, the solution to the problem is $29$.
