15 BASIC MATH OPERATIONS Your calculator uses standard chaining logic, which simply means that you enter your first value, the operator (+, -, x, *), the second value and then the Equals sign (=). A = 5. B. 3-2 = 1. C. 3 x 2 = 6. D. 3 * 2 = 1.5 This feature also makes the calculator simple to use for dimensional applications. using the construction master 5 Adding and Subtracting Strings of Dimensions Add the following measurements: 850 mm 1.2 m 600 mm Then subtract 175 mm. 850M MM 1.2m MM 600M= MM -175M= MM Pocket Reference Guide 12

16 Dividing Dimensions Divide 4700 mm into thirds (divide by 3): 4700M*3= MM Rectangular Area and Volume Find the area and volume: Length: 6200 mm Width: 3500 mm Height: 450 mm First, multiply the Length times the Width to find the Area.

20 Baluster Spacing You are going to install a handrail at the top of a balcony. Your total span is 4000 mm and you would like the space between the balusters to be about 100 mm. If each baluster is 40 mm wide, what is the exact spacing between each baluster? 1. Divide Length by spacing: oo M* MM 140M=* (29 balusters) * Desired spacing plus baluster width (100 mm plus 40 m) 2. Find total space occupied by the balusters by multiplying the width of each baluster by the rounded number of balusters: 40Mx 40. MM 29= MM 3. Find total space between all balusters: 4000M MM 1160M= MM 4.

Also applies to Inches, Feet and Yards.

35 Battery This model uses one (1) CR2016 battery (included). This should last approximately 800 hours of actual use (1 year plus for most people). Should your calculator become very dim or erratic, replace the battery. While the calculator is off, turn the calculator over and use a #1 Phillips screwdriver to remove the battery holder screw located near the center at the top. With the screw removed, pull battery holder out, remove old battery, and slide new battery into holder. The negative side of the battery should be facing you as you insert the battery holder into the calculator. Replace screw using a #1 Phillips screwdriver. Note: Please use caution when disposing of your old batteries as they contain hazardous chemicals. Replacement batteries are available at most discount or electronics stores. You may also call Calculated Industries at Reset If your calculator should ever lock up, press Reset a small hole located below the p key to perform a total reset. Pocket Reference Guide 32
