One - fourth of the sum of numbers m and n.
Product of numbers x and y subtracted from their difference.
Numbers p and q both squared and added.
Number 3 subtracted from five times the product of number a and b.
​

Answer 1

one fourth of the sum of numbers m and n. = 1/4 × (m + n)

product of numbers x and y subtracted from their difference = xy - ( x - y)

numbers p and q both squared and added. =

(√pq ) + (√ pq)

number 3 subtracted from five times the product of number a and b. = 5(ab) - 3
