The following questions are as simple as they are & nbsp; & nbsp; & nbsp; & nbsp; 81.2-11 ÷ 7-17 × 3 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 913 △ 8 + 18 × 713 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 6696 △ 62-6.5 × 10.6 [34 - (56-23)] 54

（1）81.2-11÷7-17×3，=81.2-117-37，=81.2-（117+37），=81.2-2，=79.2；（2）913÷8+18×713，=913×18+18×713，=（913+713）×18，=1613×18，=213；（3）6696÷62-6.5×10.6，=108-68.9，=39.1；（4）[34-（56-23）]÷54，=[34-16]÷54，=712×45，=715．
