The powers of 10 must be the same in both terms in order to add/subtract. Once the power of 10 matches, just add or subtract. Adjust the answer to scientific notation.

The subtraction of octal numbers follows the same rules as the subtraction of numbers in any other number system. The only variation is in borrowed number. In the decimal system, you borrow a group of 1010. In the binary system, you borrow a group of 210.

Subtracting Logs with the Same Base. To subtract logs, just divide the inputs (numbers inside the log). The rule log_b(x/y) = log_b(x) - log_b(y) lets you "convert division to log subtraction". It's actually just the "log version" of the quotient rule for exponents.

It is possible to add and subtract binary numbers in a similar way to base 10 numbers. For example, 1 + 1 + 1 = 3 in base 10 becomes 1 + 1 + 1 = 11 in binary. In the same way, 3 – 1 = 2 in base 10 becomes 11 – 1 = 10 in binary.

Quotient Rule: , this says that to divide two exponents with the same base, you keep the base and subtract the powers. This is similar to reducing fractions; when you subtract the powers put the answer in the numerator or denominator depending on where the higher power was located.

When two exponents with the same base are being divided, subtract the exponent of the denominator from the exponent of the numerator to yield a new exponent. Attach that exponent to the base, and that is your answer. In this case, subtract from .

Scientific notation is commonly used in mathematics to represent positive or negative numbers that are extremely large or close to zero. Numbers are written as a decimal number between one and 10 (including 1, but excluding 10) multiplied by some integral power of 10.

Subtracting mixed numbers works much the same way as adding mixed numbers. To subtract mixed numbers, subtract the whole number parts of the mixed numbers and then subtract the fraction parts in the mixed numbers. Finally, combine the whole number answer and the fraction answer to express the answer as a mixed number.

Once the numbers have the same base and exponents, we can add or subtract their coefficients. Here are the steps to adding or subtracting numbers in scientific notation : Determine the number by which to increase the smaller exponent by so it is equal to the larger exponent.

If a quantity is written as the product of a power of 10 and a number that is greater than or equal to 1 and less than 10, then the quantity is said to be expressed in standard form (or scientific notation). It is also known as exponential form. Note that we have expressed 65 as a product of 6.5 and a power of 10.

You simply include all the significant figures in the leading number. For example, the number 450 has two significant figures and would be written in scientific notation as 4.5 × 10 2, whereas 450.0 has four significant figures and would be written as 4.500 × 10 2.
