Decimal calculator
The result:
15 * (1 / 15 / (1 / 15 + 1 / 12 + 1 / 10)) = 4
Spelled result in words is four.Calculation steps
- Divide: 1 / 15 = 0.06666667
- Divide: 1 / 12 = 0.08333333
- Add: the result of step No. 2 + the result of step No. 3 = 0.06666667 + 0.08333333 = 0.15
- Divide: 1 / 10 = 0.1
- Add: the result of step No. 4 + the result of step No. 5 = 0.15 + 0.1 = 0.25
- Divide: the result of step No. 1 / the result of step No. 6 = 0.06666667 / 0.25 = 0.26666667
- Multiple: 15 * the result of step No. 7 = 15 * 0.26666667 = 4
This calculator makes basic and advanced operations with decimals, real numbers, and integers. It also shows detailed step-by-step information about the calculation procedures. Solve problems with two, three, or more decimals in one expression. Add, subtract and multiply decimals step-by-step. This calculator uses addition, subtraction, multiplication, or division for positive or negative decimal numbers, integers, real numbers, and whole numbers.

PEMDAS - Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
BEDMAS - Brackets, Exponents, Division, Multiplication, Addition, Subtraction
BODMAS - Brackets, Of or Order, Division, Multiplication, Addition, Subtraction.
GEMDAS - Grouping Symbols - brackets (){}, Exponents, Multiplication, Division, Addition, Subtraction.
MDAS - Multiplication and Division have the same precedence over Addition and Subtraction. The MDAS rule is the order of operations part of the PEMDAS rule.
Be careful; always do multiplication and division before addition and subtraction. Some operators (+ and -) and (* and /) have the same priority and must be evaluated from left to right.
Examples:
• addition of decimals: -1.5 + 2.45• addition followed subtraction: 5+1-2
• multiplying decimals: 0.25 * 0.2
• division of a decimals: 5.2 / 0.5
• parenthesis: 3 + 7{4 + 3[2-(8 - 4)×3] + 5}×2
• 2nd power and order of evaluation: 6^2-(2*7+4^2)
• cube root: cuberoot(27)
• Convert fraction to a decimal: 3/4
• decimals and mixed numbers: 1.5 - 1 1/5
