Scientific notation involves representing each digit in the number as a power of ten. In a decimal number, you just write the digits in order with a decimal point in the appropriate place.
The decimal point of a number separates the whole part of the number from the fractional part of the number. It is located between the units column and the tenths column of every number. A decimal place is one of the digits after the decimal point: The first decimal place is the first digit, which is the tenths digit The second decimal place is the second digit, which is the hundredths digit The third decimal place is the third digit, which is the thousandths digit etc. When showing or rounding to a number of decimal places there will be that number of digits after the decimal place. eg the number 5.671 has three decimal places as there are three digits after the decimal point and the second decimal place, for example, contains the digit 7.

The difference is the PLACE VALUE is the number in standard form and the VALUE is the name of the place spot the number is in.
No, 87 is not divisible by 7. To determine if a number is divisible by 7, you can use the rule that states a number is divisible by 7 if the difference between twice the digit in the ones place and the number formed by the other digits is either 0 or a multiple of 7. In this case, the number formed by the other digits is 8, and twice the digit in the ones place is 14. The difference between 14 and 8 is 6, which is not a multiple of 7, so 87 is not divisible by 7.

If the digits go from the thousands place to the ones place then we need to use 4 digits. Because the digits are all even, we are forced to use the 4 even digits (2, 4, 6 and 8). As they decrease by 2 each time, the only option for ordering them is greatest to lowest. Therefore, the number described in the question is 8,642.
The 11 finger trick is a math trick where you can quickly multiply numbers by 11. To use the trick, you separate the digits of the number you want to multiply by 11, add the two digits together, and place the result in between the original digits. This works because 11 is the same as 10 1, so when you add the two digits together and place the result in between, you are essentially multiplying the original number by 10 and then adding the original number to it.
A single digit in a number can have a place value. A number with several digits cannot.
