9×8+7+6+5+4+3+2+1+0=100 is the answer because i started from the highest to the lowest.

THE ANSWER IS 9 x 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 – 0=100

i worked the answer out, i work out that 9×8=72+7=79=85+5=90+4=94+3=97+2=99+1=100+0=100 so
9×8+7+6+5+4+3+2+1+0=100

0u 1u 2u 3u 4u 5u 6u 7u 8u 9u.I will put a u=used when i use the number.
1.9 x 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 – 0 = 100

8×9=72 72+7=79 79+6=85 85+5=90 90+4=94

Claire, I really like the way that you showed us that you tried more than one way to get to 100 using the given digits. Great effort!!!

Great effort Gregory, good to see that you looked at another slightly different sequence . But instead of the ‘=’ sign , you need a plus sign. Can you figure out why? Great stuff!!!
