Hey! Here's the answer: http://urjnaswxkfjjknseochallenge.blogspot.com/201...
Hey there!
Here's the answer to your question:
4 + 5 ( 12 x 7) - 453
= 4 + [5 * (12 * 7)] - 453
= 4 + [5 * 84] - 453
= 4 + 420 - 453
= 424 - 453
= -29
Multiplication and division precede addition and subtraction. Hence, the grouping.
Hope it helps.
Have a nice and blessed day!
Good luck,

4 + 5(12 x 7) - 453 = (use PEMDAS)
4 + 5(84) - 453 =
4 + 420 - 453 =
424 - 453 = -29

You have to use your order of operations:
Brackets come first:
12 x 7 = 84
Then multiplication:
5 x 84 = 420
Then addition/subtraction (in whichever order they're originally in):
4 + 420 = 424
424 - 453 = - 29

It's a rum question Anonymous, and my answer is: 4 + 5 ( 12 x 7) - 453? Take care.

Hello,
To work out this equation: 4+5(12x7)-453 you must do the following:
According to BODMAS/BIDMAS brackets ALWAYS go first, so you must work out 12x7 first. Next you must multiply that answer by 5 (Because any number outside the first bracket means you must multiply what is inside). Now add 4. Lastly subtract 453 to give you your answer.
So to sum up:
1) Brackets: 12x7=84
84x5=420
2) Addition: 4+420=424
3) Subtraction: 424-453= -29
So the answer is: -29
