You should use your calculator for such simple sums. It is far quicker and involves fewer key depressions than posting the question on WA. I could tell you the answer but how can you be sure that I did not make a mistake? Or that I am not messing about?
100 100 004 001 ------- 205 -------
1200.
200 + n = 100 + 200200 + n = 300n = 300 - 200n = 100
Yes. Good job.
Well, 1+1+1+2+3 equals 8, so 800.
100+1000=1100
100 100 004 001 ------- 205 -------
1200.
100 + 100 = 200
150 + 200 + 100 + 130 = 580
200 + n = 100 + 200200 + n = 300n = 300 - 200n = 100
Yes. Good job.
Well, 1+1+1+2+3 equals 8, so 800.
The answer is 1166.
100 + 100, 50+50+50+50, or 120+ 90
800
200 + 200 + 200 + 200 + 200 = 1000
