1,760 × 8,800 = 15,488,000. You can easily arrive at this result, if you like, through mental calculations: First, of all, 1760 × 8800 = 176 × 88 × 1,000 = 2 × 88 × 88 × 1,000. Now, what is a painless way to find 88² ? 88² - 12² = (88 - 12)(88 + 12) = 76 × 100 = 7,600. Thus, 88² = 7,600 + 12² = 7,744. Now, double 7,744, and add 3 zeroes. Magically, you get 15,488,000, which is your answer. After all, 2(7,500 + 244) = 15,000 + 488. You can easily confirm this with your calculator.
