Bodmas- addition and subtraction have same value

Division multiplication have same value too.

When sums have the same value you solve from

LEFT TO RIGHT !!!!

To solve 300 - 2 * 60 + 5, follow the standard order of operations (PEMDAS/BODMAS): evaluate multiplication before addition and subtraction, then work from left to right.

Multiplication: 2 \times 60 = 120

Subtraction: 300 - 120 = 180

Addition: 180 + 5 = 185

The final result is 185.

23p-7q-(21p-9q)

=(23p-21p)+(-7q+9q). This is because:

(23p+21p)+ -7q-(-9q) = -7q-(-9q) = -7q-+9q
