脱式计算过程如下:
①824÷4×3
=204×3
=612
②(601-246)÷5
=355÷5
=71
③1500-125×8
=1500-1000
=500
④540÷(65-59)
=540÷6
=90
⑤66×5+774
=330+774
=1104
⑥760-540+1110
=220+1110
=1330
⑦789-13×45
=789-(10+3)×45
=789-(10×45+3×45)
=789-(450+135)
=789-585
=204
⑧(25+33)×26
=58×(20+6)
=58×20+58×6
=1160+348
=1508
⑨201+232-365
=433-365
=68
⑩300-(300-222)
=300-300+222
=222
