1) 421-(572+139) :79;
2) 58•17-666:37;
3) 342:(326-269)•187;
4) (297:99+520:65)•67;
5) 8014-132•54+44 892:36;
6) 1285-282•75:47+14 472:18;
7) (199 430-119•805) :(148+8536:88);
8) (770+126 828:542) :(406•117-47 000).

1) $$421-(572+139):79=421-711:79=421-9=412.$$

2) $$58\cdot 17-666:37=986-18=968.$$

3) $$342:(326-269)\cdot 187=342:57\cdot 187=6\cdot 187=1122.$$

4) $$\left(297:99+520:65\right)\cdot 67=(3+8)\cdot 67=11\cdot 67=737.$$

5) $$8014-132\cdot 54+44892:36=8014-7128+1247=886+1247=2133.$$

6) $$1285-282\cdot 75:47+14472:18=1285-450+804=835+804=1639.$$

7) $$\left(199430-119\cdot 805\right):\left(148+8536:88\right)=\left(199430-95795\right):\left(148+97\right)=103635:245=423.$$

8) $$\left(770+126828:542\right):\left(406\cdot 117-47000\right)=\left(770+234\right):\left(47502-47000\right)=1004:502=2.$$
