Add and subtract (i)m−n,m+n(ii)mn+5−2,mn+3EasyAnswer

Add and subtract (i)m−n,m+n(ii)mn+5−2,mn+3EasyAnswerPart(i)

Add and subtract (i)m−n,m+n(ii)mn+5−2,mn+3EasyAnswerPart(i)Add

Add and subtract (i)m−n,m+n(ii)mn+5−2,mn+3EasyAnswerPart(i)Add=m−n+m+n=2m

Add and subtract (i)m−n,m+n(ii)mn+5−2,mn+3EasyAnswerPart(i)Add=m−n+m+n=2mSubtract

Add and subtract (i)m−n,m+n(ii)mn+5−2,mn+3EasyAnswerPart(i)Add=m−n+m+n=2mSubtract=m−n−m−n=−2n

Add and subtract (i)m−n,m+n(ii)mn+5−2,mn+3EasyAnswerPart(i)Add=m−n+m+n=2mSubtract=m−n−m−n=−2nPart(ii)

Add and subtract (i)m−n,m+n(ii)mn+5−2,mn+3EasyAnswerPart(i)Add=m−n+m+n=2mSubtract=m−n−m−n=−2nPart(ii)Add

Add and subtract (i)m−n,m+n(ii)mn+5−2,mn+3EasyAnswerPart(i)Add=m−n+m+n=2mSubtract=m−n−m−n=−2nPart(ii)Add=mn+5−2+mn+3=2mn+6

Add and subtract (i)m−n,m+n(ii)mn+5−2,mn+3EasyAnswerPart(i)Add=m−n+m+n=2mSubtract=m−n−m−n=−2nPart(ii)Add=mn+5−2+mn+3=2mn+6Subtract

Add and subtract (i)m−n,m+n(ii)mn+5−2,mn+3EasyAnswerPart(i)Add=m−n+m+n=2mSubtract=m−n−m−n=−2nPart(ii)Add=mn+5−2+mn+3=2mn+6Subtract=mn+5−2−mn−3=0

Add and subtract (i)m−n,m+n(ii)mn+5−2,mn+3EasyAnswerPart(i)Add=m−n+m+n=2mSubtract=m−n−m−n=−2nPart(ii)Add=mn+5−2+mn+3=2mn+6Subtract=mn+5−2−mn−3=0Hence, this is the answer.
