Certainly! Let's break down the given expression step by step using the BODMAS rule (Brackets, Orders - i.e., powers and square roots, Division and Multiplication, Addition and Subtraction):
### For part (a):
Given expression:
[tex]\[ 220 - 70 \div 35 - 49 \times 2 \][/tex]
1. Division first:
[tex]\[ 70 \div 35 = 2 \][/tex]
2. Substitute the division result back into the expression:
[tex]\[ 220 - 2 - 49 \times 2 \][/tex]
3. Multiplication next:
[tex]\[ 49 \times 2 = 98 \][/tex]
4. Substitute the multiplication result back into the expression:
[tex]\[ 220 - 2 - 98 \][/tex]
5. Subtraction last (left to right):
[tex]\[ 220 - 2 = 218 \][/tex]
[tex]\[ 218 - 98 = 120 \][/tex]
So, the final result for part (a) is:
[tex]\[ 120 \][/tex]
### For part (b):
Please provide the expression for part (b), so I can break it down step by step using the BODMAS rule similarly.
