Why a Spreadsheet?

• A spreadsheet is the computer equivalent of a paper ledger sheet. It consists of a grid made from columns and rows. It is an environment that can make number manipulation easy.

• If you change the mg/day amount, you will have to start the math all over again. On the computer version you can change the values and the result is automatically re-calculated.

• Let the COMPUTER do the calculations

Basics of a Spreadsheet

· Spreadsheets are made up of

–columns

–rows

–and their intersections are called cells

· In each cell there may be the following types of data

–text (labels)

–number data (constants)

–formulas (mathematical equations that do all the work)

Types of Data you will type

Three basic types of data that can be entered:

· labels -(text with no numerical value)

e.g., “Life Stage Group”, or “0-6 months”

· constants -(just a number --constant value)

e.g., “210”, or “270”

· formulas* -(a mathematical equation used to calculate)

e.g., “=10+100”, or “=123*12+78.2

Basic Math

Spreadsheets have many Math functions built into them. Of the most basic operations are the standard multiply, divide, add and subtract. These operations follow the order of operations (just like algebra).

Examples

A1 (column A, row 1) = 5 A2 (column A, row 2) = 7 A3 (column A, row 3) = 8 B1 (column B, row 1) = 3 B2 (column B, row 2) = 4 B3 (column B, row 3) = 6
