What are the rules of adding subtracting dividing and multiplying written in scientific notation?
1 With addition change the scientific notation back to 'normal numbers' and then add accordingly
2 With subtraction change the scientific back to 'normal numbers' and then subtract accordingly
3 With division subtract the exponents and divide the decimals
4 With multiplication add the exponents and multiply the decimals
5 Note that if changes occur below 1 or greater than 9 in the decimal element of the scientific notation then appropriate adjustments must be made
What else can I help you with?
What is the benefit of writing number in scientific notation?
Ask yourself. Would you rather write this out in long hand? 234,000,000,000,000,000,000 ----------------------------------- Or this? 2.34 X 1020 -------------- Let alone adding, subtracting, multiplying and dividing the first long number.
What is the disadvantage of using scientific notation?
If you are adding or subtracting two numbers in scientific notation, you must rewrite one of the numbers to the same power of ten as the other, before performing the addition (or subtraction).
When multiplying numbers in scientific notation what do you do with the exponent?
Add them
When dividing in scientific notation what do you do with the exponents?
You subtract the exponent of the denominator from that of the numerator.
When adding or subtracting numbers written in scientific notation the exponents must be the?
Same.
Does the negative rule for exponents using scientific notation apply to adding subtracting dividing and multiplying?
Yes, it does.

When multiplying numbers in scientific notation what do you do with the exponent?
Add them
When subtracting numbers in scientific notation what you do with exponents?
yes its really important
When dividing in scientific notation what do you do with the exponents?
You subtract the exponent of the denominator from that of the numerator.
When adding or subtracting numbers written in scientific notation the exponents must be the?
Same.
Rules in adding or subtracting scientific notation?
When adding or subtracting numbers in scientific notation, ensure that the exponents are the same. If the exponents are not the same, adjust one or both numbers to match. Then, add or subtract the coefficients while keeping the exponent the same. Finally, simplify the result if necessary by converting it back to proper scientific notation.
Solving one step inequalities?
To solve one-step inequalities, you isolate the variable on one side of the inequality by performing the same operation on both sides. This can involve adding, subtracting, multiplying, or dividing by a number. When multiplying or dividing by a negative number, remember to reverse the inequality sign. The solution will be expressed in terms of the variable and can be represented on a number line or interval notation.
When dividing number in scientific notation what must you do with the exponents?
Subtract them.
Why would multiplying numbers in scientific notation be easier than multiplying them the regular way?
Multiplying numbers in scientific notation is easier when the numbers are very, very large or very, very small. Multiplying 0.000000000385 x 0.0000000474 is a pain. Multiplying 3.85 x 10-10 x 4.74 x 10-8 is not.
How do you solve a problem using scientific notation?
Multiplying each factor by powers of ten
