An abacus was a precursor to the calculator, as it was a device used to make mathematical calculations before technology became more advanced. The device is composed of a frame intersected with rows of wires. These wires are strung with beads. These beads can be slid across the wire to sep...
Now, multiply the numerators: 1 x 3. Your product will be 3. Next, move two columns to the right. In essence, you will skip a row of beads, and place your first product: 3. This is “giving one for the abacus.) Now, place the 3 there. Multiply the denominators: 4 x 2. Your...

(Try to multiply XI by LVII or to divide CXLIII by IX; it simply cannot be done with pencil and paper. ) The Romans did all of their arithmetic on an abacus, the ancient counterpart of the modern computing machine. Their number system discouraged the study of pure mathematics....
Thanks for your appreciation. You are getting the error with asterisk because your formula attempts to multiply by 1 (*1) directly within the MID function’s parameters, that is not correct. You need to apply the multiplication outside of the MID function but within the array operation. ...
Method 3 – Editing the Name Box to Autofill Numbers in Excel We have a list of pizza prices and want to calculate the final prices with 7.5% VAT. Steps: Multiply C5 with 1.075 (for 7.5% VAT, the multiplier will be 1.075) at Cell D5. You’ll get the price including VAT for the ...
Multiply each numeric letter grade from Steps 1 to 4 by the number of credit hours received for the course. For example, if you received a C in a 4-credit-hour course, you would multiply 2 x 4 to get 8. This figure represents the grade point for the particular course. Calculate the...
