Answer 2

To evaluate the expression 74263:721:(721:7)+199-105, let's break it down step by step:

Step 1: Evaluate the expression 721:7. 721 divided by 7 is 103.

Step 2: Substitute the value obtained from Step 1 into the expression. 74263:721:103+199-105

Step 3: Evaluate the expression 74263:721:103. 74263 divided by 721 is 102.

Step 4: Substitute the value obtained from Step 3 into the expression. 102:103+199-105

Step 5: Evaluate the expression 102:103. Since 102 is less than 103, the ":" operator typically denotes a range. In this case, it represents the inclusive range from 102 to 103.

Step 6: Substitute the range obtained from Step 5 into the expression. [102, 103]+199-105

Step 7: Perform the addition operation. 102 + 199 = 301 103 + 199 = 302

Step 8: Substitute the results of the addition operation into the expression. [301, 302] - 105

Step 9: Perform the subtraction operation. 301 - 105 = 196 302 - 105 = 197

Therefore, the final result is either 196 or 197, depending on the range interpretation in Step 5.
