I was taught BEDMAS

Brackets
Exponents
Division
Multiplication
Addition
Subtraction

This makes this:

2*3+2(7)+7
= 6+14+7
= 27

Order of solution: BODMAS

Brackets Of Division Multiplciation Addition Subtraction

So:
Solve Brackets
=2x3+2(7)+7

Then Of : Nothing there
Then Division: Nothing there
Then Multiplication: 6+14+7
Then Addition: 27
Then Subtraction: N/A

Just remember, BODMAS

EDIT: XD... it extremely is arithmetic issues, suitable? the x is a multiplication sign. the thrill of internet. 12(7-2x3) i understand curiously complicated on the commencing up look, inspite of the undeniable fact that it extremely is extremely common. you purely might desire to you are able to word the order of operations. yet some human beings can't memorize stuff and that i do no longer motivate you to no longer understand what you do. Maths are superb once you get the belief of it. it extremely is many times multiplications and divisions until now sums and subtraction and you many times remedy interior the parentheses until now something. Why? properly, in case you get the belief, you will by no ability forget approximately back - and, extra powerful, in case you loose it in an examination, you have got the potential to teach to your self what you are able to desire to do. First, the parentheses. 7-2x3 Why will we do the 2x3 first? properly, considering the fact it extremely is a type in its very own. 2 and 3 are factors of 6; it extremely is purely an prolonged thank you to jot down 6... it could seem stupid now to try this, yet later on, manipulating numbers to get factors rather of total would be sensible. For now, purely see that 2x3 is a type. So, the minus sign for the great expression 2x3, so it extremely is -6. Then, we've 7-6 it extremely is ordinary which you will remedy... it extremely is a million. Now, 12 cases what we got here across. back, why will we do the interior first? with the aid of fact the parentheses are used to show what's blanketed in one equipment. Like with multiplication, saying 12 cases (7-2x3) is the comparable as saying 12 cases a million. So, as quickly as you realize what you're doing, see what happens once you're making the mathematics of it: 12(7-2x3) 12(7-6) 12(a million) 12 -->it extremely is our answer.

6 + 14 + 7 = 27
2009-08-24 5:13 pm
2 x 3 + 2(14 - 7) + 7
= 6 + 2(7) + 7
= 6 + 14 + 7
= 20 + 7
= 27

Use BODMAS.

Brackets
Of
Division
Multiplication
Addition
Subtraction

So, first do BRACKETS:

2 x 3 + 2(7) + 7

Now MULTIPLICATION:

6 + 14 + 7

Now ADDITION:

27

Um...Assuming that you mean 2^3+2(14-7)+7 I would say finish the parenthesis first so you get; 2^3+2(7)+7 Now that that's done. Finish the exponent which is 2^3 which = 8+2(7)+7 Now obviously do the multiplying; 8+14+7 and you add it all together and get 29. There's your answer. :)
