Ten of them.
Forty palindromes.
800 * 700 = 560,000
The whole numbers between 700 and 800 are from 701 to 799. Those that begin with 8 are not included since they exceed 800. The numbers that end with 8 in this range are 708, 718, 728, 738, 748, 758, 768, 778, 788, and 798, totaling 10. Therefore, there are 10 whole numbers between 700 and 800 that end with 8, and none that begin with 8.
100 + 700 = 800
700 + 800 = 1500/2 = 750
Forty palindromes.
It is the same distance from 700 to 800.
The halfway point between 700 and 800 is (700 + 800) ÷ 2 = 750
800 of them.
800 * 700 = 560,000
The whole numbers between 700 and 800 are from 701 to 799. Those that begin with 8 are not included since they exceed 800. The numbers that end with 8 in this range are 708, 718, 728, 738, 748, 758, 768, 778, 788, and 798, totaling 10. Therefore, there are 10 whole numbers between 700 and 800 that end with 8, and none that begin with 8.
Do the subtractions - 735 - 700, versus 800 - 735, and see which is less.
100 + 700 = 800
850.
700 + 800 = 1500/2 = 750
800
The multiples of seven between 700 and 800 are: 707, 714, 721, 728, 735, 742, 749, 756, 763, 770, 777, 784, 791 and 798.
