Final answer:
To solve 18,923,612 - 9,089,689, subtract the second number from the first number.
Step-by-step explanation:
To solve the expression 18,923,612 - 9,089,689, we subtract the second number from the first number. Starting from the rightmost digit, we subtract 9 from 2. Since 2 is smaller than 9, we borrow 1 from the next digit to the left, making it 11 - 9 = 2. Continuing with the subtraction, we get 12 - 8 = 4, 12 - 6 = 6, and 1 - 0 = 1. So the result is 9,833,923, which matches option B.
