Question

Verify the following.
(a) 7291 +354 = 354 + 7291
(b) 33+ (8251 +67) = (33 +67) + 8251
(c) (516 + 484) + 3377 = 516 + (484 +3377)​

Answer 1

Answer:

(a)7291+354=354+7291

= 7645=354+7291

=7645=7645

(b)33+(8251+67)=(33+67)+8251

=33+8318=(33+67)+8251

=8351=(33+67)+8251

=8351=100+8251

=8351=8351

(c)(516+484)+3377=516+(484+3377)

=1000+3377=516+(484+3377)

=4377=516+(484+3377)

=4377=516+3861

=4377=4377
