Many students think that mathematical calculation is difficult. I sorted out some mixed operation problems of rational numbers. Let's have a look.

Mixed operation of rational numbers [-| 98 |+76+(-87)] * 23 [56+(-75)-(7)]-(8+4+3)

5+2 1*8/2-6-59

68/2 1-8- 1 1*8+6 1

-2/9-7/9-56

4.6-(-3/4+ 1.6-4-3/4)

Rational number calculation problem (5+3/8*8/30/(-2)-3

(-84)/2*(-3)/(-6)

1/2*(-4/ 15)/2/3

- 1+2-3+4-5+6-7

-50-28+(-24)-(-22)

Rational number addition and subtraction mixed operation test questions 1, (-7)-(+5)+(-4)-(- 10)

2、—4.2+5.7—8.4+ 10

3、 12—(— 18)—(—7)— 15

4、4.7—(—8.9)—7.5+(—6)

5、—4 1+65—43+6 1

The above is some information about rational number calculation, I hope it will help you.
