360
60+60+60+60+60+60+60+60 =480 All the addition can happen in the same step. This is the same as 60*8.
300 !
6000.......it's actually 5,100
4100
60 + 60 + 60 + 50 + 50 + 40 + 30 = 350
1000+40=1040 1040+1000=2040 2040+30=2070 2070+1000=3070 3070+20=3090 3090+1000=4000 4000+10=4100
1000 + 1000 - 1000 + 1000 = 2000
The result of the equation - 130 plus 80 plus 60 plus 60, is found as follows;130 + 80 + 60 + 60= ( 130 + 80 ) + 60 + 60= 210 + ( 60 + 60 )= 210 + 120= 330Answer = 330
-30 plus 60 = 30
180
1000% = 1000/100 = 10 10 x 6 = 60 1000% of 6 is 60.
