Question

Simplify using the BODMAS rule: 40 – {(25 ÷ 5) of 4} + 10 ​

Answer 1

Step-by-step explanation:

You have to apply the rule BODMAS here to solve this kinda problems.

B -Bracket

O-Of

D-Division

M-Multiplication

A-Addition

S-Subtraction

Hence the rule in word becomes solve the part which is in bracket first. Then ‘Of’s.

After that Divide, Multiply, Add & Subtract.

Hence here the equation is

40÷5×4+10

Since there is no bracket and of here so start with division part.

40÷5 becomes 8.

Hence the equation becomes

8×4+10

Now multiply 8×4=32

And finally equation becomes

32+10

=42

Answer 2

Step-by-step explanation:

$40 -( (25 \div 5)of \: 4) + 10 \\ 40 -( 5 \times 4) + 10 \\ 40 - 20 + 10 \\ 40 - 10 \\ 30$
