    1. 2 tens is 20, so how many two digit numbers are less than 20? That's just 10 - 19. So, there are 10 numbers (10, 11, 12, 13, 14, 15, 16, 17, 18, 19) that are less than 2 tens.

    2. For the sum to be of two or three equal addends, the number should be divisible by either 2 or 3. This is because x + x = 2x and y+ y+ y = 3y, right?

    Now for a number to be divisible by 2, it has to be even. So, the even numbers between 7 and 13 are 8, 10, and 12.

    For those divisible by 3, we have 9 and 12.

    Putting them together, we have 8, 9, 10 and 12, or 4 numbers.

    3. If a book has 50 pages, then we can say that the page numbers are 1 to 50, right? 1-9 has 1 digit each, and 10 - 50 has 2 digits each.

    Now 1-9 is 9 numbers, and 10 -50 is 41 numbers. So we just solve

    9 x 1 + 41 x 2 = 9 + 82 = 91.

    Hope this helps!

    From 10 to 50 there are

    There are 41 numbers. 1 number = 2 digits

    = 41 * 2 digit

    = 82 digits

    = 9 digits

    = 91 digits in total
