原式 =(25x4)x(16x5) =100x8x2x5 =800x10 =8000

16x25x5x125 =(4x25)x5x(125×4) =100×5×500 =250000

53x54十54x16+69x25+21x69 =54×(53+16)+69×(25+21) =54×69+69×46 =69×(54+46) =69×100 =6900

(25-15)×16 (20×5)×(7×3) 35×(100-1) 24×(100+2) 25×4×2+4

(x-16)x5=45 解:x-16=45÷5 x-16=9 x=25

原式 =1.25x5.6+2.5x3.6-0.25x3.6 =1.25x8x0.7+2.5x4x0.9-0.25x4x0.9 =10x0.7+10x0.9-1x0.9 =7+9-0.9 =16-0.9 =15.1 供参考。
