Why do you need to calculate the brackets first in 45 plus 67 plus 34 equals 146?

You don't. Addition is transitive (as is multiplication) and so you do not need to calculate brackets first as long as the sum has only additions (or only multiplications).
But what is 5 - 3 - 2
(5 - 3) - 2 = 2 - 2 = 0
or
5 - (3 - 2) = 5 - 1 = 4
So, in the case of subtraction, it is important to know which operator is done first. Brackets indicate the intended order when there is ambiguity.

How To Solve x2-7x plus 10 equals 28?
First you need to make it equal 0 by subtracting 28 from the left. x2-7x-18 = 0 Then you need to factorise it by finding two numbers that add to make -7 and multiply to make -18 and writing it in brackets like this. (x-9)(x+2) = 0 Then you reverse the signs of the numbers in the brackets to get the two answers (this is a quadratic equation because it has an x2 so it will have two answers). 9 and -2
What is one-half of one-third of one-fourth of 690?
this is a simple answer. you first do the problem one half of one third, which equals 0.166666667, then you do one fourth of one third, which equals 0.0833333333, then you do one fourth of 690, which equals 172.5 which would be your final answer. You need to take the problem step by step and solve it with a calculate or division to make it easier.

How does one calculate the surface area of a sphere?
To calculate the surface area of a sphere, you first need to determine its radius. Once you know the radius, you need to square it, or multiply it by itself. Next, you will need to multiply it by 4. Finally, you will multiply that number by pi, or 3.14.
What you do is time 4 times 13 and it equals 39?
If you do do 4 × 13 = 39 you will get it wrong. Working it out: 4 × 13 = 52 To get 39, you need to calculate: 3 × 13 = 39.
