(iii) If more than one grouping symbol is present in an expression we remove the inner-most grouping symbol first and collect combine like terms if any. We continue this process outwards until all the grouping symbols have have been removed.

(ii) If a - sign precedes a symbol of grouping the grouping symbol may be removed and the sign of each term is changed.

Simplify each of the following algebraic expressions by removing grouping symbols. 2x+(5x-3y) 2. 3x-(y-2x)

Simplify each of the following algebraic expressions by removing grouping symbols. 1. 2x+(5x-3y) 2. 3x-(y-2x)

(i) If a + sign precedes a symbol of grouping the grouping symbol may be removed without any change in the sign of the terms.

Simplify each of the following algebraic expressions by removing grouping symbols. a-[b-{a-(b-1)+3a}] a-[2b-{3a-(2b-3c)}]

In each question below, a group of digits/symbols is given, followed by four combinations of letters numbered (a), (b), (c) and (d). You have to find out which of the combinations (a), (b), (c) and (d) correctly represents the group of digits/symbols based on the following coding system and the conditions those follow and mark the number of that combination as your answer. If none of the four combinations correctly represents the group of digits/symbols, mark (e) i.e., "None of these as the answer Conditions (i) If the first unit in the group is an even digit and the last unit is a symbol, both these are to be coded as the code for the symbol. (ii) If the first unit in the group is an odd digit and the last unit is an even digit their codes are to be interchanged. (iii) If both the first and the last units in the group are symbols, both these are to be coded as or @91$26
