how many numbers from 1 to 200 have an expanded form that is identical to a standard form? What are they? can you help me understand it?
Certainly, I can help you understand how to find the numbers from 1 to 200 that have an expanded form identical to their standard form.
To find such numbers, let's first understand what expanded form and standard form mean in this context:
- Standard form: This refers to the usual way of writing a number, with digits in a conventional order. For example, the number 68 is written in standard form as "68".
- Expanded form: This involves writing a number as the sum of its place values. For example, the number 68 can be written in expanded form as "60 + 8".
Now, to identify the numbers from 1 to 200 that have an identical expanded form and standard form, we need to check each number and compare how it is written in both forms. Let's go through the process step by step:
1. Start with the number 1 (the lowest number in the range).
2. Write its expanded form by expressing it as the sum of its place values: "1".
3. Check if the expanded form is identical to its standard form. In this case, it is, so we can say that the number 1 has an identical expanded and standard form.
4. Repeat the process for all the numbers in the range up to 200.
By following the steps above, you can find all the numbers from 1 to 200 that have an identical expanded form and standard form.
