Why Choose the TI-108SC Online Calculator?

The free TI-108SC online calculator replicates all features of the original Texas Instruments hardware including the unique MDAS toggle and 3 display indicators. This emulator delivers the exact MDAS order-of-operations engine, 8-digit LCD display, and color-coded key layout of the physical device. No download, signup, or cost required.

MDAS Order of Operations

Toggle between sequential left-to-right calculation and proper algebraic order of operations. When MDAS is ON multiplication and division are calculated before addition and subtraction, following standard math rules.

Three Display Indicators

The TI-108SC LCD shows M for memory, a dash for negative values and E for error states on the left side of the display, replicating the exact indicators of the physical device.

Four-Function Arithmetic

Perform addition, subtraction, multiplication and division with the same color-coded red and white key layout as the physical TI-108SC.

Three-Key Memory System

Store and recall numbers using M+, M- and MRC. Memory overflow triggers the E error indicator, matching the exact behavior of the physical TI-108SC.

Full Keyboard Support

Use keyboard shortcuts including backtick to toggle MDAS, M and N for memory plus and minus, B for MRC, # for sign change and Space or Z for clear.

Works on Any Device

Fully responsive on smartphones, tablets and desktops. The calculator is always visible on mobile with a fullscreen button above it for an immersive experience.

How Does the TI-108SC Online Calculator Work?

The TI-108SC online calculator works in 4 steps: set the MDAS toggle to your preferred mode, enter your first number, press an operator, then press equals. In MDAS ON mode the calculator resolves multiplication and division before addition and subtraction. No setup is required.

⚙️

Set Your MDAS Mode

Click the OFF/MDAS toggle switch to choose your calculation mode. OFF means left-to-right. MDAS ON means the calculator follows proper order of operations.

🔢

Enter Your Number

Type your first number using the white digit keys. The LCD shows M, dash and E indicators on the left side of the display.

Choose an Operation

Press a red operator key. In MDAS ON mode the calculator stores the operation for proper precedence. In OFF mode it calculates immediately left to right.

Press Equals

Press the red = key or Enter to see the result. Press ON/C once to zero the display or twice to clear all running calculations.

The TI-108SC is a basic solar-powered calculator from Texas Instruments. It features a 4-function arithmetic engine, an MDAS toggle switch that enables algebraic order of operations, 3 LCD display indicators for memory, negative values and errors, and an 8-digit display. The TI-108SC shares the same royal blue body and color-coded key layout as the TI-108 and is designed for students learning order of operations in elementary and early middle school.
SC stands for Solar Calculator in the TI-108SC model designation. The SC suffix indicates the calculator is primarily powered by ANYLITE solar technology built into the strip at the top of the device. ANYLITE converts both indoor and outdoor light into electricity to power the calculator without batteries.
Yes. The TI-108SC is a four-function calculator that performs addition, subtraction, multiplication and division.
