After studying this chapter you will be able to understand: What is cell alignment? What is the purpose of Fill handle? Why comments are inserted in the excel sheet? Why hyperlinks are used? | Calculations & Graphics using Spreadsheet ADE100- Computer Literacy Lecture 17 Knowledge test What is cell alignment? What is the purpose of Fill handle? Why comments are inserted in the excel sheet? Why hyperlinks are used? 2 2 Topics covered Doing mathematics Formulas, addition, subtraction Average, logic formula, etc. Making charts formatting . background, Legend, color of bars, creating pictograph 3 Formulas Formula Expression that produces some values Use values, cell references and built-in functions Must begin with an equal sign (=) When the formula is entered in the cell the calculation executes immediately Cells display result and formula bar shows formula 4 Entering formulas Entering a formula Click on the empty cell that will display the result of the formula Type the equal sign (=) Type your formula without any spaces like a1+a2+a3 and press Enter key If you change any value of a cell referenced in a formula, the formula will automatically recalculate and display the . | Calculations & Graphics using Spreadsheet ADE100- Computer Literacy Lecture 17 Knowledge test What is cell alignment?
