(18 + 23) + 7



Choose exactly two answers that are correct.







A.
30 + 25 (use the commutative property)





B.
41 + 7 (use order of operations)





C.
25 + 30 (use the distributive property)





D.
18 + 30 (use the associative property

Answer 1

I will give a medal

Answer 2

if you are the one who is going to solve it, how will you solve it?
Remember PEMDAS

Answer 3

48 @Data_LG2

Answer 4

yes, but the question is HOW did you get 48? :)
what did you do first? did you evaluate the terms inside the brackets first?

Answer 5

yes
@Data_LG2

Answer 6

so if you evaluate the bracket only, what did you get?

Answer 7

41

Answer 8

so it will be 41 + 7... so which of the choices is right?

Answer 9

b

Answer 10

:)

Answer 11

but I have to have 2 answers' @Data_LG2

Answer 12

you can also apply this property of addition: \(\sf (A+B) + C =A + (B +C)\)

so for your question, it will look like this: \(\sf (18+23) + 7 =18 + (23 +7)\)
then do the same thing.. evaluate the bracket first for \(\sf 18 + (23 +7)\)
