Using the scientific calculator
استخدام الآلة الحاسبة العلمية
This calculator supports the core operations you'd expect on a handheld scientific calculator: addition, subtraction, multiplication, division, parentheses for controlling order of operations, powers using the ^ symbol, square roots, and the trigonometric functions sine, cosine and tangent, which are evaluated in radians. It also includes base-10 logarithms (log) and natural logarithms (ln), plus the constant π for quick access when working with circles or periodic functions.
Build an expression by tapping the keys in order — for example 2 × (3 + √(16)) − sin(0) — then press "=" to evaluate. The display shows your full expression on the small line above and the running entry on the large line below, so you can see exactly what will be calculated before committing. Press "⌫" to remove the last character if you make a mistake, or "C" to clear everything and start over.
Order of operations follows standard mathematical convention (parentheses, then exponents, then multiplication/division, then addition/subtraction), so you rarely need extra parentheses beyond what the calculation actually requires. Keep in mind results are rounded to 10 decimal places to avoid floating-point display noise, which is more than enough precision for everyday calculations, homework, or quick engineering estimates.
