Explanation

Input devices receive data from the user or environment and send it to the CPU.

Explanation

Step 1: Calculate the first expression

First, we add 73 to 89, which gives 73+89=162

Step 2: Double the sum and verify the resul

.Then, we double this amount: 162 x 2=324

Next, we calculate the square of 18, which is 18^{2}=18 x  18=324

Explanation

Explanation

$$0.004\times 0.5=0.002$$

Explanation

The sequence divides each term by 3:

• $486÷3=162$

• $162 ÷ 3 = 54$

• $54÷3=18$

• $18 ÷ 3 = 6$

• $6÷3=2$

Explanation

Mid-term breaking is a method used to factorize quadratic expressions like  ax^2+bx+c.

It involves splitting the middle term into two terms whose product equals a×c.
