Answer 1

Answer:

10.36×12÷6-4

36×2-4

72-4

68

12..successor of 99 is 100

predecessor of 99 is 98

product is 100×98=9800

13.1 is the identity element of multiplication and 0 is the identity element of addition

14.0

15.0

16.44×105=4620

39×98+39×2=3900

280×57-280×7=14000

17.4001+3768+2999+1232=12000

4×694×125×2=694000
