Question

supply reasons for each of the first four steps given here.
(575+37)+75=525+(37+75)
=525+(75+37)
=(525+75)+37
=600+37
=637

Answer 1

\[(575+37)+75=525+(37+75)\] the parentheses moved
that is the associative law of addition

Answer 2

\[525+(37+75) =525+(75+37)\] the \(37\) and \(75\) switched places
that is the commutative law of addition

Answer 3

\[ 525+(75+37) =(525+75)+37\] parentheses moved again
again the associative law

Answer 4

\[(525+75)+37 =600+37\] is not property, that is addition as \(525+75=600\)

Answer 5

as is \(600+37=637\)

Answer 6

this seemed like pretty easy problem at first
