The Mathematical Expression Calculator is for entering a complete numeric formula in one field instead of pressing a basic calculator through one operation at a time. It handles arithmetic, parentheses, powers, common functions, pi, e, and several familiar implicit-multiplication forms.
Supported input includes:
+, -, *, /, and ^;();sin(), cos(), tan(), sqrt(), log(), ln(), abs(), ceil(), floor(), round(), and exp();pi and e;2pi, 2(3+4), 2sqrt(9), and (1+2)(3+4).Each successful calculation is added to the current page’s recent history, with the newest result first and up to 10 entries retained for quick checking and copying.
2 + 3 * (4 - 1)^2.For variables, equations, symbolic simplification, matrices, integrals, or derivatives, use a specialist tool. For keypad-style DEG/RAD, factorial, permutation, combination, or memory work, use the Scientific Calculator; for fraction arithmetic, decimal-place rounding, or dedicated logarithm input, see the Fraction Calculator, Rounding Calculator, and Logarithm Calculator.
It evaluates numeric expressions made from numbers, operators, parentheses, common functions, and pi/e constants. It is not a variable or symbolic-algebra solver.
Yes. These common forms are treated as implicit multiplication. Add explicit parentheses whenever division and implicit multiplication could be grouped in more than one way.
sin, cos, and tan use radians, so sin(pi/2)=1. Convert degree inputs to radians before evaluating.
log is base 10 and ln is the natural logarithm, so log(100)=2 while ln(e)=1.
No. The page evaluates finite numeric expressions and does not provide variable assignment, equation solving, symbolic simplification, or graphing.
Evaluate numeric expressions with parentheses, powers, common functions, pi/e constants, implicit multiplication, and recent history.
