Question

(11) 10578 + 99999
(1) 6784 + 9999
6. For any whole numbers a, b, c, is it true that (a + b) + c = a +(c + b)? Give reasons,
7. Complete each one of the following magic squares by supplying the missing numbers:​

Answer 1

Step-by-step explanation:

11) 110577

1) 16783

6. Yes. let's take an example

let's take 3 whole numbers 7, 4 and 16

7=a , 4=b, 16= c

(a+b)+c = a+(b+c)

(7+4)+16 = 7+(4+16)

using the rule of Bodmas we will solve bracket first on both sides.

(11)+16= 7+(20)

Now we will open the bracket

11+16 = 7+20

27=27

LHS =RHS

HENCE PROVED

you can take any three numbers as an example but the answer will always remain LHS=RHS.
