Place value is the category the number the digit is in. For example, take 123. The 1 is worth one hundred, the 2 is worth 20 and the 3 is worth 3. Actual value is the number itself in that position. So, as an example, "What digit is in the hundreds place of the number 123?" The answer would be 1.
120
It means that depending on its position, a digit will have a "multiplier value" that will make it worth more or less. In the number "123", the place-value of the digit 3 is 1, the place-value of digit 2 is 10, and the left-most place-value - for the digit 1 - is 100. In other words, the mere fact that there are other numbers to the right of the "1" make it worth more.
It is 100.

Break each place value into it's own group. So, you get: 3+4=7. That is your final ones place value 2+3=5. That is your final tens place value 1+2=3. That is your final hundreds place value. Now put them to together and you get 357.
In decimal form, the number 123 is written as "one hundred twenty-three." This format follows the standard naming convention for numbers in the English language, where each digit's place value is represented by a specific word (e.g., "hundred" for the hundreds place, "twenty" for the tens place, and "three" for the ones place). This representation helps clearly communicate the value of the number based on its positional notation within the decimal system.

Moving the place of a digit ups its value by a factor of ten. For example, in the number 123, the 2 has a value of 20 since it is in the tens place. However, if the number was 213, the two would have a value of two hundred, since it is now in the hundreds place.
It is 100.
