# Adding, Subtracting, Dividing, and Multiplying Scientific Notation Calculator

Calculator Preferences
Scientific Notation Calculator

This calculator will perform scientific notation math (add, subtract, multiply, and divide). Plus the calculator shows its work so you can learn the steps to solving each type of operation. The Learn tab includes short tutorials for each of these exponential notation math operations:

• Subtracting SN
• Multiplying SN
• Dividing SN

#### Selected Data Record:

A Data Record is a set of calculator entries that are stored in your web browser's Local Storage. If a Data Record is currently selected in the "Data" tab, this line will list the name you gave to that data record. If no data record is selected, or you have no entries stored for this calculator, the line will display "None".

1st SN:1st SN:1st scientific notation:Enter first scientific notation:

#### Enter first scientific notation:

Enter the first scientific notation of the equation and then tap the operation (+, −, ×, or ÷) that you wish to perform on the two entries. Note that you can enter scientific notation in any of these formats:
• 35e7
• 35E7
• 35x10^7
 First scientific notation
2ns SN:2nd SN:2nd scientific notation:Enter second scientific notation:

#### Enter second scientific notation:

Enter the second scientific notation of the equation. Note that you can enter scientific notation in any of these formats:
• 35e7
• 35E7
• 35x10^7
 Second scientific notation

This is the result achieved by performing the selected operation on the two entered notations.

This is the answer as returned by the programming language this calculator is created in -- which may return a scientific notation, and/or an oddly rounded result. I provide it so you can compare it to the answer I came up with by manipulating text strings instead of calculating with numbers.

If you would like to save the current entries to the secure database, tap or click on the Data tab, select "New Data Record", give the data record a name, then tap or click the Save button. To save changes to previously saved entries, simply tap the Save button. Please select and "Clear" any data records you no longer need.

Help and Tools

#### Help and Tools:

This section, which you can Unstick or Hide in the Calculator Preferences (just above the top of the calculator), contains the following tabs (content too long to fit within bordered frame can be scrolled up and down):

About: Click this tab for an introduction to the calculator.

Instructions: Click this tab for step-by-step instructions for using the calculator.

Terms: Click this tab for a list of the descriptions that are located within each popup help button (info icons).

PCalc: Click this tab for a handy "pocket" calculator you can use when you need to calculate an entry needed for the calculator.

Data: Click this tab to save a set of entries or a note in between visits. Entries and notes will be stored to your web browser's local storage (if supported by your browser of choice), meaning they can only be recalled with the same device and web browser you were using when you saved them. If you'd like to save entries and notes between devices you can do so by subscribing to the Ad-Free Member Version.

Move the slider to left and right to adjust the calculator width. Note that the Help and Tools panel will be hidden when the calculator is too wide to fit both on the screen. Moving the slider to the left will bring the instructions and tools panel back into view.

Also note that some calculators will reformat to accommodate the screen size as you make the calculator wider or narrower. If the calculator is narrow, columns of entry rows will be converted to a vertical entry form, whereas a wider calculator will display columns of entry rows, and the entry fields will be smaller in size ... since they will not need to be "thumb friendly".
