20 + 45 = 65 20 x 45 = 900
600/50 = 12
Let the unknown number be n.Then 20 + n = 30 : Subtract 20 from both sides gives :-20 - 20 + n = 30 - 20 : n = 10
No.
10 and 20.
The sum of 30 and 45 is 75.
25 and 20 25 + 20 = 45 25 - 20 = 5
25 and 20 25 + 20 = 45 25 - 20 = 5
20 + 45 = 65 20 x 45 = 900
The words, "sum of" mean 'the added together value of'... For instance, "What is the sum of 15, 20 and 45?" The method is to add each of these figures together: EG. 15 + 20 + 45 The answer, of course, is 80 ... written: 15 + 20 + 45 = 80, or 15+20+45=80
