Answer 2

36×27+37×73
=36ⅹ27+36x73+73
=36ⅹ(27+73)+73
=36ⅹ100+73
=3600+73
=3673

Answer 3

=36×27+（36+1）×73
=36×27+36×73+73
=36×（27+73）+73
=36×100+73
=3600+73
=3673

Answer 4

=36*27+37*（100-27)
=36*27+3700-37*27
=3700+（36-37)*27
=3673

Answer 5

36×27+37×73＝（37-1）×27+37×73＝37×27-1×27+37×73＝37×（27+73）-27＝37×100-27＝3700-27＝3673
