Decimal calculator
The result:
3 + 7{4 + 3[2-(8 - 4)×3] + 5}×2 = -291
Spelled result in words is minus two hundred ninety-one.Calculation steps
- Subtract: 8 - 4 = 4
- Multiple: the result of step No. 1 * 3 = 4 * 3 = 12
- Subtract: 2 - the result of step No. 2 = 2 - 12 = -10
- Multiple: 3 * the result of step No. 3 = 3 * (-10) = -30
- Add: 4 + the result of step No. 4 = 4 + (-30) = 4 - 30 = -26
- Add: the result of step No. 5 + 5 = -26 + 5 = -21
- Multiple: 7 * the result of step No. 6 = 7 * (-21) = -147
- Multiple: the result of step No. 7 * 2 = -147 * 2 = -294
- Add: 3 + the result of step No. 8 = 3 + (-294) = 3 - 294 = -291
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. This online decimals calculator will help you understand adding, subtracting, multiplying, or dividing decimals.
The calculator follows well-known rules for the order of operations. The most common mnemonics for remembering this order of operations are:
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 evaluate 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
