1000
an easy way to do this is to add 5 plus 5 which = 10 then add the two zeros in 500 because you already used the 5 when you added them which = 1000
:)
500 plus 800 equals 1,300.
1,620
400 + 500 = 900
500+600= 1,100
1,500
548.
800
505
500 + 7878787 + 68686 + 7766 = 7,955,739
It doesn't, it equals 15.
500+50+5
4y20 = 500 => y20 = 25 => y = 20√25 = 1.1746 approx Then x = 500 - y = 489.8254 (approx).
