I am learning my doubles. I’m using my place value. As you can see this is how I work when I try to find out the answer. So I took away the 73 from 973 and the theirs 900 left. Then I took away 3 from 73 and that will leave you 70. So 900 x 2 equal to 1800. I used the 70 to times 2 and that will equal to 140. 3 x 2 will equal to 6. After that, you all them altogether, so 1800 + 140 + 6 = 1946. Then you will end up with the answer and my answer is 1946. I find this easy because I know my time table well.
