94 + 51 x 5

= 94 + 255

= 349

2)

21 + 34 - 26

= 55 - 26

= 29

3)

201 ÷ 31

= 201/31 or 6 15/31

4)

7456 + 98265 - 95222

= 105721 - 95222

= 10499

5)

4625 + 1321 - 2666

= 5946 - 2666

= 3280

6)

97322 - 54101 x 5

= 97322 - 270505

= -173183

7)

24680 + 13579 - 369

= 38259 - 369

= 37890

8)

9956 ÷ 661

= 9956/661 or 15 41/661

9)

234 ÷ 16 x 3

= (234 x 3)/16

= 351/8 or 43 7/8

10)

222 + 555 - 777 x 99999

= 222 + 555 - 77699223

= 777 - 77699223

= -77698446

11)

431 + 2225 - 66 x 9

= 431 + 2225 - 594

= 2656 - 594

= 2062

12)

9978 + 12345 - 21000

= 22323 - 21000

= 1323

13)

934 x 31

= 28954

14)

23 + 896 ÷ 95 - 7 x 10

= 23 + 896/95 - 7 x 10

= 23 + 896/95 - 70

= (23 x 95)/95 + 896/95 - (70 x 95)/95

= 2185/95 + 896/95 - 6650/95

= 3081/95 - 6650/95

= -3569/95 or -37 54/95

15)

93 + 226 x 10 ÷ 55

= 93 + 2260 ÷ 55

= 93 + 2260/55

= 93 + 452/11

= (93 x 11)/11 + 452/11

= 1023/11 + 452/11

= 1475/11 or 134 1/11
