My accounting course requires us to do excel work and I am completely lost.

Click on the 'SLN' tab and enter your name in Cell C1. If Cell C1 is left blank, you will not be able to see your score. Each yellow cell requires a formula. The formula must only contain cell addresses. Each correct formula will begin with,-+ , or - The basic mathematical operators are,,+- , and / Addition: 70 add the values in cells A1 and B4, the formula is =A1+B4 Subtraction: To subtract the value in cell B.4 from the value in cell A1, the formula is =A1-B.4 Multiplication: To multiply the values in celis A1 and B4, the formula is =A1*B4 Division: To divide the value in cell A1 by the value in cell B4, the formula is =A1/B4 Using the 5LM function The SUN function has the following syntax: -SLN(COST, SALVAGE,LIFE) Each variable may be either a value or a formula that returns a value. Using absolute addresses Once a formula is created, you will often want to copy the formula to other columns and rows. It's important to understand that excel always uses "relative addresses" unless you indicate otherwise by creating an "absolute address". For example, if you are calculating the cost of purchasing 2 boxes of cereal at a cost of $3.95 per box, the formula in cell B28 is =826B27. Aithough we read cell B28 as Multiply 2 boxes by $3.95, Excel fs actually calculating the value in cell B28 as "Multiply the value in the cell in the same column (column B) 2 rows above (row 26) by the value in the cell in the same column 1 row above (row 27 ). This works just fine to calculate the cost of 2 boxes, but if we copy the formula in cell B28 to C28, Excel will assume relative references. The formula in cell C28 will become =C26C27. Since Cell C27 is blank, the formula will return a value of $0 (which is an excellent deal for 6 boxes of cereal, but it isn't accurate!) Adding a $ sign before the column or row reference locks the formula to a specific location. If we modify the formula in cell B2B to =32658527 before we copy the formula, Excel will not change the row or the column of the second variable. When the formula is copied to columns C through E, the formulas become: CellC28=C26$B$27CellD28=D26$B$27CellE28=E26$8$27 Sometimes, you will want the column to stay fixed, but allow the row to remain relative when it's copied. If so, add a dollar sign jefore the column, but not the row (1.e.SB27) If you want the row to stay fixed, but allow the column to remain relative when it's sopied, add a dollar sign before the row, but not the column (i.e. B\$27). Tapping the F4 button while entering the formula (or in the ormula bar) toggles among the 3 absolute options (Absolute Column and Absolute Row $B$28, Absolute Column and Relative Row B28, Relative Column and Absolute Row BS28)
