25 tens, or 250
50 + 200 = 250
It is 250.
4 hundreds means 4x100=400. Two tens mean 2x10=20 Thus, their sum would be 400+20=420.
20 + 5 = 25
It is: 5+15 = 20
The sum means the result of adding the numbers. Therefore the sum of 20 and 15 is 35. 5 times 35 is 175 - therefore 5 multiplied by the sum of 20 and 15 is 175.
20 Five has a half of a ten.
The sum is 50+20 = 70
4 hundreds means 4x100=400. Two tens mean 2x10=20 Thus, their sum would be 400+20=420.
The sum of -5 and 20 is 15. The distance between -5 and 20 is 25. The sum of the numbers between -5 and 20 is 180. The sum of the numbers from -5 to 20 is 195.
40
20 + 5 = 25
Sum means add them together.15+20=35
It is: 5+15 = 20
10x20 + 5x10 =200 + 50 =250
The sum means the result of adding the numbers. Therefore the sum of 20 and 15 is 35. 5 times 35 is 175 - therefore 5 multiplied by the sum of 20 and 15 is 175.
4 and 5 have the sum of 9 and the product of 20.
20 Five has a half of a ten.
1 + 23 + 4 + 5 + 67 = 100 is one way. 1 + 2 + 34 + 56 + 7 = 100 is another. 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28 so you need to move two non-adjacent digits that sum to 8 into the tens' places. This is because: Start with a sum of 28 Lose two digits that sum to 8 from the units so that you have 28 - 8 = 20 Gain two digits that in the tens place that sum to 8 so that 20 + 80 = 100.
