FutureStarrHow Do You Put 1 3 in a Calculator
A calculator with a built-in square root function is a pretty handy device. It's useful for calculating approximate answers, like in the question "how many square inches of tile would it take to cover a 20' x 20' area"?
Calculating numbers that contain fractions can be tricky, even when you’re using a calculator. You may be able to write a fraction on a calculator using the fraction button. If your calculator doesn’t have this feature, use an online calculator if you’re allowed to do so. As another option, you might turn the fraction into a decimal or turn the fraction into a percent. A variation on the above method is to break the calculation into two parts, and use the memory functions of the calculator to store the result of the first part. The calculator memory is particularly useful when you want to calculate the values of several expressions that have a common part. This common part need be entered only once and its value reused several times subsequently. For example, rewriting the formula for the volume of wood contained in a log as
You could write down the answer to the first part of the calculation on paper, and enter it into the calculator again. However, it is possible that you may make an error either in writing down the number or in typing it into the calculator. A better method is to use the fact that the calculator retains the last calculated answer, which can then be inserted in the subsequent calculation using the If a severe error is made when entering a calculation into the calculator, it may prevent the answer being calculated at all, as the calculation may not make mathematical sense. In such circumstances a ‘Syntax Error’ will be displayed as shown in Figure 6. The Syntax Error screen gives you two options: (Source: www.open.edu)
