# 1/2 + 1/4 + 1/8 + 1/16 + ⋯

This calculator divides fractions. The first step makes the reciprocal value of the second fraction - exchange numerator & denominator of 2nd fraction. Then multiply both numerators and place the result over the hàng hóa of both denominators. Then simplify the result to the lowest terms or a mixed number.

Divide: 50% : 1/3 = 1/2 · 3/1 = 1 · 3/2 · 1 = 3/2 Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 1/3 is 3/1) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the following intermediate step, it cannot further simplify the fraction result by canceling.In other words - one half divided by one third is three halfs.
Rules for expressions with fractions: Fractions - use a forward slash lớn divide the numerator by the denominator, i.e., for five-hundredths, enter 5/100. If you use mixed numbers, leave a space between the whole and fraction parts.Mixed numerals (mixed numbers or fractions) keep one space between the integer andfraction & use a forward slash to input đầu vào fractions i.e., 12/3 . An example of a negative mixed fraction: -5 1/2.Because slash is both signs for fraction line và division, use a colon (:) as the operator of division fractions i.e., 1/2 : 1/3.Decimals (decimal numbers) enter with a decimal point .

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 & Division have the same precedence over Addition và Subtraction. The MDAS rule is the order of operations part of the PEMDAS rule. Be careful; always vì chưng multiplication & division before addition and subtraction. Some operators (+ and -) and (* & /) has the same priority và then must evaluate from left lớn right.
