Explanation:

Sub - Question 1: Find the Sum of \(892,422 + 54,770\)

Step 1: Align the numbers by place value

We have \(892,422\) and \(54,770\). Aligning them:
\[

$$\begin{align*} &\quad892,422\\ &+\quad54,770\\ \end{align*}$$

\]

Step 2: Add the corresponding place values

Starting from the rightmost digit (units place):

• Units place: \(2 + 0=2\)
• Tens place: \(2+7 = 9\)
• Hundreds place: \(4 + 7=11\), carry over \(1\) to the thousands place, write down \(1\)
• Thousands place: \(2+4 + 1\) (carried over) \(=7\)
• Ten - thousands place: \(9+5 = 14\), carry over \(1\) to the hundred - thousands place, write down \(4\)
• Hundred - thousands place: \(8+0+1\) (carried over) \(=9\)

So, \(892,422+54,770 = 947,192\)

Sub - Question 2: Find the product of \(827\times23\)

Step 1: Multiply \(827\) by \(3\)

\(827\times3=2481\)

Step 2: Multiply \(827\) by \(20\)

\(827\times20 = 16,540\)

Step 3: Add the two results

\(2481+16,540=19,021\)

Sub - Question 3: Write the number \(4,000,000 + 300,000+10,000 + 500+30 + 7\) in standard form

Step 1: Add the numbers

• \(4,000,000+300,000=4,300,000\)
• \(4,300,000 + 10,000=4,310,000\)
• \(4,310,000+500 = 4,310,500\)
• \(4,310,500+30=4,310,530\)
• \(4,310,530 + 7=4,310,537\)

Answer:

s:

• \(892,422 + 54,770=\boxed{947192}\)
• \(827\times23=\boxed{19021}\)
• The standard form of \(4,000,000 + 300,000+10,000 + 500+30 + 7\) is \(\boxed{4310537}\)
