SOALAN 1 : 7m + 23n + 12 + 3m + 12n

SOALAN 2 : (11m + 10n) + (5m + 21n)

 

SOALAN 1 : 9m - 12n - 3m - 11n

SOALAN 2 : (32q - 21p) - (20q - 12p)

 

SOALAN 1 : m(2 x 6n) + 2(7n + 8m)

SOALAN 2 : 9m x 3n x 10m x 7n

 

SOALAN 1 : 14p / 7p + 64q / 8q

SOALAN 2 : (128p + 26q + 18r + 42s) / 2

Addition Soalan 1 : 7m + 23n + 12 + 3m + 12n = 7m + 3m + 12n + 23n + 12 = 10m + 35n + 12 Soalan 2 : (11m + 10n) + (5m + 21n) = 11m + 5m + 10n + 21n =16m + 31n

Subtraction Soalan 1 : 9m - 12n - 3m - 11n = 9m - 3m - 12n - 11n = 12m - 23n Soalan 2 : (32q - 21p) - (20q - 12p) = 32q - 21p - 20q + 12p = 32q -20q + 12p - 21p = 12q - 9p

Multiplication Soalan 1 : m(2 + 6) + 2(7n + 8m) = (2 x m + 6 x m) + (2 x 7n + 8m x 2) = 2m + 6m + 14n + 16m = 8m + 16m + 14n = 24m + 14n Soalan 2 : 9m x 3n x 10m x 7n = 9m x 10m x 3n x 7n = 90m x 21n

Division Soalan 1 : 14p / 7p + 64q / 8q = 2p + 8q Soalan 2 : (128p + 26q + 18r + 42s) / 2 = 128p / 2 + 26q / 2 + 18r / 2 + 42s / 2 = 64p + 13q + 9r + 21s
