Maths Guide: Addition and Subtraction with Bridging and Borrowing

What is the first step in adding three-digit numbers with bridging?

• Start with the largest value

• Use column labels

• Add the hundreds first

• Ignore the tens column

When adding 452 and 19, what should you do if the sum of the ones column is a two-digit number?

• Ignore the tens digit

• Start over

• Partition the number and carry over the tens

• Write both digits in the ones column

In the example of adding 468 and 56, what is the result of adding the tens column?

• 110

• 120

• 130

• 140

What is the term used for splitting a number into tens and ones during addition?

• Aligning

• Partitioning

• Borrowing

• Bridging

What is a crucial step to remember when starting subtraction with borrowing?

• Subtract from the top number

• Always start with the largest value

• Subtract from the bottom number

• Ignore the ones column

In subtraction, what should you do if the top number is smaller than the bottom number in a column?

• Skip the column

• Borrow from the next column

• Add a placeholder zero

• Reverse the numbers

When subtracting 452 and 35, what is the result of the ones column after borrowing?

• 7

• 6

• 5

• 8

What is the final result of subtracting 431 and 46?

• 385

• 365

• 395

• 375

Why is it important to use column labels in both addition and subtraction?

• To make the process faster

• To make the numbers look neat

• To avoid mistakes in alignment

• To skip unnecessary steps

In subtraction, what does borrowing involve?

• Adding a zero to the column

• Ignoring the tens column

• Taking a ten from the next column

• Reversing the numbers
