Grade VI TLE ICT spreadsheet topic

1. Spreadsheet program processes and carries out
calculations on the data entered by the user. For
example, a computer model of a school’s budget
might show that the school might run out of money
before the end of the term if it hires an extra
teacher.

2. Microsoft Excel is one of the most powerful and most
popular electronic spreadsheet tool available. It offers
unmatched spreadsheet, database, and chart creation
abilities all rolled into one software application.
Spreadsheets are made up of columns and rows of
numbers. Free alternatives include OpenOffice Calc and
Google Docs, which runs in a web browser.

3. **What is a Formula?
Worksheets use formulas to perform
calculations on the data you enter. With
formulas, you can perform addition,
subtraction, multiplication, and division using
the values contained in various cells.

4. Formulas typically consist of one or more
cell addresses and/or values and a
mathematical operator, such as +
(addition), - (subtraction), *
(multiplication), and / (division). Every
formula must begin with an equal sign
(=).

6. Functions are ready-made formulas that perform a series of
operations on a specific range of values. For example, to determine
the sum of a series of numbers in cells A1 through H1, you can enter
the function =SUM(A1:H1), instead of entering =A1+B1+C1+ and so
on.
Every function consists of the following three elements:
1.The = sign indicates that what follows is a function.
2.The function name (for example, SUM) indicates the operation that
will be performed.
3.The argument (for example, A1:H1), indicates the cell address of
the values that the function will act on. The argument is often a
range of cells, but it can be much more complex.

7. Functions are ready-made formulas
that perform a series of operations on a
specific range of values. For example, to
determine the sum of a series of
numbers in cells A1 through H1, you can
enter the function =SUM(A1:H1), instead
of entering =A1+B1+C1+ and so on.

8. AVERAGE: Calculates the mean
or average of group of numbers.
=SUM:Adds the values and
calculates the total in a range of
cells.
