Subtraction: Basic subtraction

To solve the problem 98 - 45, we'll apply a step-by-step subtraction method:

First, align the numbers:

   98
- 45
-----

Now, subtract starting from the rightmost digits (ones place):

• Subtract the ones place: 8 - 5 = 3
• Subtract the tens place: 9 - 4 = 5

Therefore, the total difference is 53.

Thus, the solution to the problem is $53$.

To solve the problem of finding $86 - 34$, we can follow these steps:

• Align the numbers by place value:
• 86 (|Tens|Ones|)
• - 34 (|Tens|Ones|)
• Step 1: Subtract the ones place. $6 - 4 = 2$.
• Step 2: Subtract the tens place. $8 - 3 = 5$.

Putting the results together, the difference is $\mathbf{52}$.

Therefore, the correct answer to the subtraction $86 - 34$ is $52$.

To solve the subtraction problem $79 - 57$, follow these steps:

• Step 1: Align the numbers by place value.

Write: $\begin{array}{c} & 7 & 9 \\ - & 5 & 7 \\ \hline \end{array}$

• Step 2: Subtract starting from the units place.

Subtract $7$ from $9$:
$9 - 7 = 2$.
Place $2$ in the units position.

• Step 3: Subtract the tens place.

Subtract $5$ from $7$:
$7 - 5 = 2$.
Place $2$ in the tens position.

Thus, after performing the subtraction, the result is $22$.

Therefore, the solution to the problem $79 - 57$ is $22$.

To solve this subtraction problem, let's follow these simple steps:

• Step 1: Identify the numbers involved in the subtraction. Here, we need to subtract 60 from 66.
• Step 2: Perform the subtraction calculation. That is, calculate $66 - 60$.

Let's work through the steps:

Step 1: We are given two numbers: 66 (the minuend) and 60 (the subtrahend).

Step 2: Subtract the subtrahend from the minuend:

$66 - 60 = 6$

Thus, the difference between 66 and 60 is $6$.

To solve the subtraction problem $58 - 8 =$, we follow these steps:

• Identify the operation: We need to subtract 8 from 58.
• Perform the subtraction: Start from the rightmost digit of 58, which is 8 in the ones place.
• Subtract 8 from 58 directly:

We do this operation in a straightforward manner since it is a simple subtraction:

$58 - 8 = 50$

Therefore, the result of $58 - 8$ is $50$.

The correct answer is $50$.
