Question

-18.1 - 5 step by step

Answer 1

explain in word form please

Answer 2

how did you get -23.1

Answer 3

To subtract \( 5 \) from \( -18.1 \), you can follow these steps:

1. **Understand the operation**: Subtracting a positive number is the same as adding its negative. So, \( -18.1 - 5 \) can be rewritten as \( -18.1 + (-5) \).

2. **Combine the numbers**: Since both numbers are negative (the first is \( -18.1 \) and the second, \( -5 \)), you can add their absolute values:
- The absolute value of \( -18.1 \) is \( 18.1 \).
- The absolute value of \( -5 \) is \( 5 \).
- Now add these values: \( 18.1 + 5 = 23.1 \).

3. **Add the negative sign**: Since both numbers are negative, the result is also negative:
\[
-18.1 - 5 = -23.1
\]

Thus, the final answer is:
\[
-18.1 - 5 = -23.1
\]

Answer 4

Sure! Here's a step-by-step explanation in word form:

1. **Start with the first number**: We have negative eighteen point one. This means we are dealing with a value that is less than zero.

2. **Subtract the second number**: We want to subtract five from negative eighteen point one. Subtracting a positive number (like five) from a negative number will result in a larger negative number.

3. **Think of it as addition**: Instead of thinking of subtraction, we can think of it as adding a negative number. So, subtracting five can be seen as adding negative five.

4. **Combine the two values**: Now, we combine negative eighteen point one and negative five. Since both numbers are negative, we add their absolute values (which are eighteen point one and five) together.

5. **Calculate that total**: When we add eighteen point one and five, we get a total of twenty-three point one.

6. **Apply the negative sign**: Because we started with two negative values, our total also remains negative. Therefore, the result of subtracting five from negative eighteen point one is negative twenty-three point one.

So, in summary, when we subtract five from negative eighteen point one, we end up with negative twenty-three point one.

Answer 5

Let's break it down clearly so you can see how we arrive at \(-23.1\) when we perform the operation \(-18.1 - 5\):

1. **Start with the initial value**: The initial number is \(-18.1\). This represents a value that is below zero.

2. **Subtract \(5\)**: When you subtract a positive number from a negative number, you essentially move further left on the number line. In this case, you want to subtract \(5\) from \(-18.1\).

3. **Convert to addition**: Subtracting a positive number is the same as adding a negative number. Thus, the operation \(-18.1 - 5\) can be rewritten as:
\[
-18.1 + (-5)
\]

4. **Add the absolute values**: Since both numbers are negative:
- The absolute value of \(-18.1\) is \(18.1\).
- The absolute value of \(-5\) is \(5\).
- When you add the absolute values together, you get:
\[
18.1 + 5 = 23.1
\]

5. **Determine the sign**: Because both numbers were negative, the result will also be negative. Therefore, we apply the negative sign to the result:
\[
-23.1
\]

Putting it all together, when you subtract \(5\) from \(-18.1\), you get \(-23.1\).

So, the complete calculation is:
\[
-18.1 - 5 = -23.1
\]
