6 + 6 + 6 + 6 + 1000 = 1024
6+6+6+(81-91)+1000; First add together the sixes 18+(81-91)+1000; Next we add the terms in parenthasis 18+(-10)+1000; Since we have a negative 10, we chang the sign to minus 18-10+1000; Now we subtract 18-10 8+1000; Finally, 1000+8 = 1008 1008
5 x 6 + 1000 = 1030
1010
Its 500,500. you just work 1000 x 1001 divided by 2
6000.......it's actually 5,100
4100
1000 + 1000 - 1000 + 1000 = 2000
1000+40=1040 1040+1000=2040 2040+30=2070 2070+1000=3070 3070+20=3090 3090+1000=4000 4000+10=4100
500,500
13011
5+3/10+6/100+9/1000
5000 + 8250 + 100 + 1000 + 6500 + 1000 + 6500 + 1500 + 1500 + 10000 + 1000 + 10000 + 100 + 8250 + 5000 + 5000 + 8250 = 78,950
