[" 1.Add: "],[[" (i) "(2sqrt(3)-5sqrt(2))" and "(sqrt(3)+2sqrt(2)),2sqrt(3)]]

Add 2sqrt(2)+5sqrt(3) and sqrt(2)-3sqrt(3)

Add (i) (2sqrt(3)-5sqrt(2)) and (sqrt(3) + 2sqrt(2)) (ii) (2sqrt(2) + 5sqrt(3) - 7 sqrt(5) and (3sqrt(3)-sqrt(2) + sqrt(5)) (iii) ((2)/(3) sqrt(7) -(1)/(2)sqrt(2)+6sqrt(11)) and ((1)/(3)sqrt(7) + (3)/(2)-sqrt(11))

(i) Rationalise (sqrt(3)-sqrt(2))/(sqrt(3)+sqrt(2))

(sqrt(3)-sqrt(5))(sqrt(3)+sqrt(5))/(sqrt(7)-2sqrt(5))

(-sqrt(3)+sqrt(-2))+(2sqrt(3) + i)

Add 2sqrt(2)+5sqrt(3) and sqrt(2)-3sqrt(3) .

Multiply : (sqrt(3)+sqrt(2)) (5sqrt(2)+sqrt(3))

Multiply : (sqrt(3)+sqrt(2)) (5sqrt(2)+sqrt(3))

(sqrt(5)-sqrt(2))(sqrt(2)-sqrt(3)) (sqrt(5)-sqrt(3))^(2)

(sqrt(5)-sqrt(2))(sqrt(2)-sqrt(3)) (sqrt(5)-sqrt(3))^(2)
