1.
a)2½ + 2½ = 5
b) 7¼ - 7¼ = 0
c) 0,5 + 0,25 - 0,75 = 0
d) ³/₂ - ³/₈ + ⁵/₄ = ¹²/₈ - ³/₈ + ¹⁰/₈ = ¹⁹/₈ = 2 ³/₈
e) 1 + √2 - 1 = √2
f) √3 - 2 - √3 = -2
2.
a)5 + |5| = 10
5 - 2|5| = -5
b) -3 + |-3| = 0
-3 - 2 |-3| = -3
c) 2-√6 + | 2 - √6| = 0
2-√6 - 2| 2 - √6| = √6 - 2
d) 3√2 - 4 + |3√2-4| = 6√2 - 8
3√2 - 4 - 2|3√2 - 4| = -3√2 + 4
