Ine rormula must only contain cell addresses. Each correct formula will begin with $=,+$, or- The basic mathematical operators are,,$+?{}^{?}$ and / 100000 Addition: To add the values in cells $\mathrm{A}1$ and $\mathrm{B}4$, the formula is $=\mathrm{A}1+\mathrm{B}4$ 10000 Subtraction: To subtract the value in cell $B4$ from the value in cell A1, the formula is =A1-B4 5 Multiplication: To multiply the values in cells $\mathrm{A}1$ and $\mathrm{B}4$, the formula is =A1*B4 1 Division: To divide the value in cell $A1$ by the value in cell $B4$, the formula is =A1/B4 Using the DDB function The DDB function has the following syntax: $=$ SLN(COST,SALVAGE,LIFE,PERIOD,[FACTOR]) $\$40,000$ Each variable may be either a value or a formula that returns a value. The final variable, factor, is the depreciation rate. If omitted, it is presumed to be double declining balance. 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 = B26*B27. Although we read cell B28 as "Multiply 2 boxes by $\$3.95^{??}$, Excel is 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 $=C26^{?}\mathrm{C}27$. 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 $\mathrm{B}28$ to $=\mathrm{B}26?\$\mathrm{B}\$27$ 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: $\begin{array}{rl}\text{ Cell C28 }& =\mathrm{C}26^{?}\$\mathrm{B}\$27\\ \text{ Cell D28 }& =\mathrm{D}26^{?}\$\mathrm{B}\$27\\ \text{ Cell E28 }& =\mathrm{E}26^{?}\$\mathrm{B}\$27\end{array}$ 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 before the column, but not the row (i.e.\$B27) If you want the row to stay fixed, but allow the column to remain relative when it's copied, add a dollar sign before the row, but Column and Absolute Row \$B \$28, Absolute Column and Relative Row \$B28, Relative Column and Absolute Row B\$28) On January 1 of the current year, the purchased office machinery for $\$122,000$. The office machinery has an estimated useful life of 5 years and an estimated salvage value of $\$12,000$. Complete the depreciation schedule below.
