Numerical operations include the four basic arithmetic operations, fractions, functions, and integrals, with results being approximate. For example, the four arithmetic operations are addition, subtraction, multiplication, and division.
Let's try to calculate: 23.78 + 57.987 , 234 - 23.6 , 2.5 × 4 , 2 ÷ 3
1 ) First enter the formula in the editing aarea:
