803 - 20 = 783
To find the number that, when added to a certain number, equals 46, you would subtract that number from 46. In this case, the number would be 46 minus the given number. For example, if the given number is 20, then the number that, when added to 20, equals 46 would be 46 - 20 = 26. Therefore, the number that, when added to the given number, equals 46 is 46 minus the given number.
10 minus negative 10 equals 20: 10 - (-10) = 20 or rather 10 + 10 = 20. 10- (minus 10) = 20
20 minus 17 minus 3 minus 2 equals -2
30
20 centimeters minus 0.2 meters is equivalent to 20 centimeters minus 20 centimeters, which equals zero.
40
It is: 56 minus 20 = 36
13 + a + 7 = 5 + b - 20. This assumes the two numbers are different.
A number "m" plus 40 equals 60. Therefore, 60 minus 40 equals m. m therefore equals 20.
You would do 540 x .10 and this would give you 10% of that number, which equals 54. .10 = 10% .20 = 20%
x = 2
803 + 20 = 823823 - 100 = 723803 plus 20 minus 100 equals 723.
