43x52的计算并验算

你好!列竖式计算4558÷43并验算的过程应该是这样的,请你看好了!

计算:43*52=2236 验算:2236÷43=52

解:43乘52等于( 2236 ) ∵已知需求出43乘52等于多少 X * Y = Z,即X = Z ÷ Y ∴43乘52 = 43 * 52 = 43 * (50 + 2) = 43 * 50 + 43 * 2 = 2150 + 86 = 2236 经检验,43 = 2236 ÷ 52符合题意 答:43乘52等于2236

43x(52+48)=43x100=40x100x3x100=4300

307x52计算并验算=307x(50+2)=307x50+307x2=15350+614=15964 验算:15964÷52=307 所以结果等于15964符合题意

35*43=1505 竖式和验算如上面所示.

438x52=438x50+438x2=21900+876=22776

43x52十43x48 简便计算=43x(52+48)=43x100=4300

75*43+43*26-43 =75*43+43*26-43x1 =(75+26-1)x43 =100x43 =4300 祝学习进步.
