10 rounded to the nearest tens place is: 10. This is because the ones value is "0" so it does not round up.
2 to the nearest 10 is 0. When rounding a number to the nearest 10, you look at the digit in the tens place. Since 2 is less than 5, it rounds down to 0.
Places in the decimal system are based on powers of ten. 10^2 = hundreds 10^-2 = hundredths 10^1 = tens 10^-1 = tenths 10^0 = ones Since zero doesn't have a negative counterpart, the ones column stands alone.

There is no four digit number where the ones is twice the tens, the hundreds is five less than the ones, and the thousands is the sum of the tens and hundreds. int ones, tens, hundreds, thousands; for (thousands=1; thousands<10; thousands++) { /**/ for (hundreds=0; hundreds<10; hundreds++) { /**/ /**/ for (tens=0; tens<10; tens++) { /**/ /**/ /**/ for (ones=0; ones<10; ones++) { /**/ /**/ /**/ /**/ if (ones != 2 * tens) break; /**/ /**/ /**/ /**/ if (hundreds != ones - 5) break; /**/ /**/ /**/ /**/ if (thousands != tens + hundreds) break; /**/ /**/ /**/ /**/ printf ("dd\n", thousands, hundreds, tens, ones); /**/ /**/ /**/ } /**/ /**/ } /**/ } }
The general function is:1. y = a*x+bb is irrelevant and we can be removed2. y = a*xlets split x into ones and tens3. x = tens*10 + ones /e.g. 23 = 2*10 + 34. p1 = Multiplier of the onesp2 = Multiplier of the tens5. y = tens*10*p2 + ones*p1 /according to the question6. x*a = tens*10*p2 + ones*p1 /according to 2.7. (tens*10 + ones)*a = tens*10*p2 + ones*p1 /according to 3.8. tens*10*a + ones*a = tens*10*p2 + ones*p1 /regroup9. tens*10*a - tens*10*p2 + ones*a - ones*p1 = 0 /regroup10. tens*10*(a-p2) + ones*(a-p1) = 0 /regroup11. assuming "tens" and "ones" are not 0 then (a-p2) and (a-p1) must be 012. a-p2 = 0a-p1 = 013. a = p2a = p114. a = p1 = p2the answer is: when the Multipliers of ones and tens are equal then the product is called a.

A 0 in the tens place of any number represents 0 times 10, which is 0.
660. remember when rounding to the nearest ten your lowest non zero number will be in the tens place and you will look at the ones place to decide whether or not to round up. If the ones place is 5 or above, round up in the tens place. If the ones place is 0-4 keep the remaining tens place number.
Stem|Leaf 3|0 where the number of tens goes on the left and the number of ones (<10) goes on the right.
Let's take, for example the number 10. The '1' is the tens place, and the '0' is the ones place (also refereed to as the 'unit').
The number must be in the range of 781 to 799. To have 8 more tens than ones, the number must have a tens digit of 8 and a ones digit of 0. Therefore, the number is 780.
