1、2022年二年級數(shù)學(xué)下冊 7.2 幾百幾十加減幾百幾十筆算練習(xí)題 新人教版 (I) 筆算下列各題： 320 + 210 = 560 + 110 = 250 + 220 = 370 + 120 = 840 + 160 = 770 + 240 = 480 + 230 = 330 + 390 = 450 + 470 = 390 + 250 = 550 + 390 = 190 + 250 = 360 +250 = 440 +

2、 180 = 780 – 250 = 360 – 120 = 440 – 130 = 660 – 250 = 360 – 270 = 710 – 230 = 420 – 130 = 370 – 280 = 250 – 160 = 520 – 140 = 960 – 580 = 630 – 250 = 760 – 290 = 550 – 290 = 310 – 120 = 440 -250 = 答案

3、： 320 + 210 = 530 560 + 110 =670 250 + 220 =470 370 + 120 =490 840 + 160 =1000 770 + 240 =1100 480 + 230 =710 330 + 390 =720 450 + 470 =920 390 + 250 =640 550 + 390 =940 190 + 250 =440 360 +250 =610 440 + 180 =62

4、0 780 – 250 =530 360 – 120 =240 440 – 130 =310 660 – 250 =410 360 – 270 =90 710 – 230 =480 420 – 130 =290 370 – 280 =90 250 – 160 =90 520 – 140 =380 960 – 580 =360 630 – 250 =380 760 – 290 =470 550 – 290 =260 310 – 120 =190 440 -250 =190
