The TI-108 is a basic solar-powered handheld calculator made by Texas Instruments. It is designed for elementary school students in grades K through 3 and performs 4 arithmetic operations: addition, subtraction, multiplication and division. It also includes a percentage key, a square root key and a three-key memory system. The TI-108 is the standard classroom calculator for K-3 students in the United States because of its low cost, durability and color-coded key layout.
The TI-108 is approximately 40 years old, introduced by Texas Instruments in 1986. Its current external design has remained unchanged since the 1990 model. Texas Instruments preserved the same classic form factor because it proved durable and easy for young students across nearly 4 decades of classroom use.
The original TI-108 came out in 1986. Texas Instruments released an updated version in 1990 whose external design became the standard sold today. The TI-108 is the direct successor to the TI-1100II, a four-function calculator introduced by Texas Instruments in 1985 with added square root and percentage keys.
No. The TI-108 remains the standard K-3 classroom calculator in the United States. Its simplicity is a feature rather than a limitation because it helps young students learn basic arithmetic without distraction. Texas Instruments continues to sell the TI-108 new and it remains approved for standardized tests where more advanced calculators are not permitted.
Yes. The TI-108 is a four-function calculator that performs addition, subtraction, multiplication and division. Beyond these 4 operations it includes dedicated keys for percentage, square root and sign change. A three-key memory system with M+, M- and MRC completes the full feature set.
Yes. The TI-108 is approved for standardized exams where more advanced calculators are not permitted. According to Texas Instruments, the TI-108 is one of 3 accepted basic calculators for elementary math assessments, alongside the Casio HS-4 and Sharp EL-233.
The TI-108 and TI-108SC Calculator are 2 separate calculators from Texas Instruments with different capabilities. The TI-108 calculates left to right in every case. The TI-108SC adds an MDAS toggle that enables algebraic order of operations. Choose the TI-108 for K-3 sequential arithmetic. Choose the TI-108SC for students ready to practice order of operations.
The TI-108 calculates left to right because it is designed for K-3 students learning sequential arithmetic before algebraic order of operations. Basic calculators evaluate each expression in the order buttons are pressed rather than following PEMDAS rules. Entering 2 + 3 × 4 = returns 20, not 14, because the TI-108 computes 2+3 first.
The TI-108 became the K-3 classroom standard because it offers the lowest cost, highest durability and simplest key layout of the 3 elementary TI models. The TI-10 costs more. The TI-15 Explorer targets grades 3 through 6 with functions K-3 students do not need. The TI-108 color-coded keys, tamper-proof design and ANYLITE solar power make it the most practical choice for bulk K-3 classroom purchases.
The TI-108 is designed for the K-3 student group: Kindergarten through Grade 3, typically ages 5 to 9. It is the standard first calculator that introduces young learners to basic arithmetic. Texas Instruments offers the TI-15 Explorer for older students in grades 3 through 6 who require more functions.
ANYLITE solar technology is Texas Instruments' proprietary solar power system built into the TI-108. It converts both indoor and outdoor light into electricity to power the calculator, eliminating the need for batteries under normal classroom conditions. The TI-108 is always ready to use in any lighting environment.
