c) 176 +43 + 24 + 57​

Answer 1

Answer:

635+(477+523)=1635

(62+38)+(697+303)=1100

(176+24)+(43+57)=300

Answer 2

Answer:

(a)

$176 +43 + 24 + 57 \\ = (176 + 24) + (43 + 57) \\ = 200 + 100 \\ = 300$

(b)

$62 + 697 + 38 + 303 \\ = (62 + 38) + (697 + 303) \\ = 100 + 1000 \\ = 1100$

(c)

$176 +43 + 24 + 57 \\ = (176 + 24) + (43 + 57) \\ = 200 + 100 \\ = 300$
