enter your answers in the boxes.
(8+20)÷4+3
=
÷4+3
=
+ 3
=

10

Step-by-step explanation:

Ignoring the weird format, we have:

(8+20)/4  +3

=(8+20)/4 +3

=28/4 +3

=7+3

=10

(8+20)÷4+3   =  10

Step-by-step explanation:

Simplify the expression.

(8+20)÷4+3

To simplify this expression, we must take note of the mathematics rule 'BODMAS"

B stands for bracket

O stands for order(power)

D stands for division

M stands for multiplication

A stands for addition

S stands for subtraction

The rule of BODMAS simply implies that in an expression, you must first simplify the bracket, then you can now move on to simplify the powers if there is any, then you can now move on to divide if there is division, then you can now multiply if there is any multiplication in the expression, then you can now move on to  add or subtract if there are any in the expression.

Looking at the expression, following the rules of BODMAS, we will first of all add 8 and 20 together to give us 28 since they are in the bracket, and we are to start with the bracket first;

(8+20)÷4+3

28 ÷4 + 3

Then next is division

7 + 3

Then we can now add

10

Therefore simplifying the expression will give us the value of 10

It just doesn't always work. You can only really use this method if you are finding the result when multiplying TWO dinomals. Well I mean it is possible to use it, but it will just be confusing, which was a problem I faced before.  
Personally, this method actually confused me, when I used a larger dinomals. There are other rules, not sure how many tho. But the other one you should consider, when working with larger dinomals, you should use "vertical multiplication" (idk if that's what you really call it). 

Hope this helped :)
