Answer:
Step-by-step explanation:
BODMAS stands for brackets of division multiplication addition subtraction
1. [ 200 + (125 - 30) + (2 × 13) ] ÷ 3
= [200 + (95) + (26)] ÷ 3
= [200 + 95 + 26] ÷ 3
= [321] ÷ 3
= 321 ÷ 3
= 107
2. [(121 ÷ 11) + (59 × 51)] - 455
= [(11) + (3059)] - 455
= [11 + 3059] - 455
= [3070] - 455
= 3070 - 455
= 2615
3. [21 + (11 × 15) + (112 + 151)] + 111
= [21 + (165) + (263)] + 111
= [21 + 165 + 263] + 111
=[449] + 111
= 449 + 111
= 560
4. (155 - 5) + (155 ÷ 5) + (155 × 5)
= (150) + (31) + (775)
= 150 + 31 + 75
=256
