Thanks for the points DS!

I havent heard of a question like that before!Can anyone pls expalin me what the question means or exactly says , its all going above my head!!

So we'd solve this like

(-30(-7)-(210(-3))    ( now we have to multiply these)

=(210-(-630)  ( as when there are two minus signs both of them get cut and we just have plus sign so we'd do the same out here)

=210 + 630 (now simply add them)

=840  ANSWER

i hope uve understood by now but if not then pls be free to ask!

i hope this helps!

Thats really nice NinjaDevo for doing this for all of us!i'd like to give u a thumbs up for this!

I'll surely let you know if i require something to be added out here!

Thanks!

You know ND  im really tired of giving this answer!

but Anonymous ur lucky becoz ur getting my this kind of last answer so

2+2=4 ANSWER

Yes Anonymous you are correct but its just that you didnt explain the answer nicely for the asker could get it all properly but nevermind ive come to explain!

So we'd do this like

250 ÷ 100  ( so we'd reciprocate the right side and also change the sign to multiplication one)

=250/1 x 1/100  ( now we will cut 250 and 100 as much as they can be cut or reduced)

=5/1 x 1/2  (now as they can no more be reduced we directly multiply them)

=5/2  ( now we will divide them both to get our anwer)

=2.5  ANSWER

So i hope till now uve understood of how we got the answer but if not then pls be free to ask!

i hope this helps!

2 3/2 is the mixed fraction of 7/2 so you can also say like 2 3/2 is equal to 7/2
