Sharp WriteView Scientific Calculator EL-W506T

The Sharp EL-W506T has 640 advanced scientific functions and utilizes WriteView Technology. A standard scientific calculator cannot display fractions and symbols as the way they appear in a proper mathematical formula. A WriteView calculator, however, can display fractions and symbols just as they appear in a textbook.

Features:

• 640 Functions
• WriteView – type in your equations as they look in the textbook
• Table Mode displays the changes in values of a function
• Drill Mode is unique to Sharp calculators and allows a person to practice mental maths by giving basic maths questions and the user must type the answer into the calculator.
• Statistics distributions
• Up To 4×4 Matrix
• Home Button
• Vector function
• Twin power source (Solar cell & LR44 x 1)
