Step-by-step explanation:
Answer:
1933
Step-by-step explanation:
9 x (1 + 345) - 6 - 8 + 48 x 23 - 77
Use BODMAS method to solve these type of equation
B - Brackets
O - Power
D - Division
M - Multiplication
A - Addition
S - Subtraction
_________________________________________________________
Brackets - 1 + 345 = 346
Multiplication
9 x 346 = 3114
48 x 23 = 1104
Lets rewrite the equation now
3114 - 6 + 1104 - 77
Addition
6 + 1104 = 1110
Subtraction
3114 - 1104 = 2010
2010 - 77 = 1933
Answer = 1933
