How do you write a formula that indicates which calculations should be done first?
Brackets (aka parentheses),
eg 30 - 4 x 5 would normally be 30 - 20 ie 10, but (30 - 4) x 5 would be 26 x 5 ie 130
Use parentheses to if you would like to change the normal order of calculating answers.
Here is the order of mathematical operations:
- Parenthesesat
- Exponents
- Multiplication and Division
- Addition and Subtraction
Here two examples of how you would change the order of operations for an equation to achieve different results with the same numbers and operators:
EXAMPLE 1:
1 + 6 * 2 = 1 + 12 = 13
(1 + 6) * 2 = 7 * 2 = 14
EXAMPLE 2:
3 * 2 + 4 / 2 = 6 + 2 = 8
(3 * (2 + 4)) / 2 = (3 * 6) / 2 = 18 / 2 = 9

What is the mathematical rules for performing multiple calculations within a formula?
BiDMAS - It stands for:BracketsIndiciesDivideMultiplyAddSubtractThe rule states that you must perform the calculations within a formula in the sequence stated. i.e. anythign in Brackets has to be calculated first, then any indicies (or powers) have to be calculated, then any divisions, multiplications, additions and subtractions.....in that order.
How many combinations would it take to play every possible outcome to the ncaa bracket?
According to my calculations, with the first four included. It should be 33,396 combinations
Was the formula e equals mc2 a math formula or a science formula?
scientist one don't know how should i know! scientist two should i answer it! scientist three: uuummm? Answer2: A science formula. Einstein's idea of the conversion of mass to energy came first. The math followed the science.
How can you use parentheses to simplify calculations?
Parentheses can be used to group numbers and operations in a calculation, indicating the order in which to perform those operations. By prioritizing the calculations within parentheses first, you can simplify complex expressions, making them easier to manage. This can help prevent errors and clarify which parts of the calculation should be completed first, leading to more accurate results. For example, in the expression 2 + (3 × 4), calculating the multiplication first gives you 2 + 12 = 14, rather than performing addition first.
What is formula for cos3x?
looks like the exponents did not show up, in the first it should be 4 cosine cubed x - 3cosx and the sin 3x should be 3sinx - 4sine cubed x
How should most calculations be calculated?
Count the first 4 digits in the answer :)

How could you find the deflection in a fight of stairs using hand calculations?
You can find the deflection in a flight of stairs using hand calculations by first measuring all angles and lengths. These can then be entered into a formula which calculates deflection based on these variables.

first we should understand the question,then we should know the formula.
Who was the first machine developed for calculations?
Ashutosh Kumar
Should the first of letter a sentence be capitalized if an apostrophe precedes it?
No, the first letter of a sentence should not be capitalized if an apostrophe precedes it. The apostrophe indicates a contraction or possession and does not affect the capitalization rules for sentences.

Should a comma be put between a first name and Jr?
Yes, a comma should be placed between a first name and "Jr." when it follows the name as it indicates a generational suffix. For example, "John Smith, Jr."
