1.which formula would you use to round the number in cell b5 to the nearest 10?
2.which of the following terms means: an approximate number rather than an exact answer?
3.what is the purpose of the autosum feature in microsoft excel?

3.AutoSum is a function in Microsoft Excel and other spreadsheet programs that automatically enters the appropriate formula or function into your spreadsheet. 1.ROUND is the major rounding function in Excel that rounds a numeric value to a specified number of digits.

Syntax: ROUND(number, num_digits)

Number - any real number you want to round. This can be a number, reference to a cell containing the number or a formula-driven value.

Num_digits - the number of digits to round the number to. You can supply a positive or negative value in this argument:

If num_digits is greater than 0, the number is rounded to the specified number of decimal places.
For example =ROUND(15.55, 1) rounds 15.55 to 15.6.

If num_digits is less than 0, all decimal places are removed and the number is rounded to the left of the decimal point (to the nearest ten, hundred, thousand, etc.).For example =ROUND(15.55, -1) rounds 15.55 to the nearest 10 and returns 20 as the result.
If num_digits equals 0, the number is rounded to the nearest integer (no decimal places).
For example =ROUND(15.55, 0) rounds 5.55 to 16.

The Excel ROUND function follows the general math rules for rounding, where the number to the right of the rounding digit determines whether the number is rounded upwards or downwards. Rounding digit is the last significant digit retained once the number is rounded, and it gets changed depending on whether the digit that follows it is greater or less than 5:

If the digit to the right of the rounding digit is 0, 1, 2, 3, or 4, the rounding digit is not changed, and the number is said to be rounded down.
If the rounding digit is followed by 5, 6, 7, 8, or 9, the rounding digit is increased by one, and the number is rounded up.

2. about. approximately. around. I would go with "about" because it has a lot of verbal coverage.

Try waiting for it for a few minutes and try signing up again if that doesn’t work then leave a rating on the app and a note about the issue. hopefully they will get back to you soon with suggestions that can you. -hope this
