My Maths


I.A.L.T subtract

This is my maths.
I found this easy because I know how to subtract my number.
Next time I will use a calculator  to see if I got my maths right

Leroy, once you knew how to use this strategy you were able to confidently answer all your problems. Next time you could use bigger numbers and also numbers where you have to borrow.
Keep up the great work.

Leroy, it is great that you can use this strategy of place value to expand both sides. But there is another way you can use place value, but expanding only the right side.

e.g

8761 - 321
Expand 321 into 300+20+1

761 - 300 = 461 (take away hundreds number)

461 - 20 = 441 (take away tens number)

441 -1 = 440 (take away ones number)

Add 8,000 + 440 = 8,440

Try this with a problem like:

4332 - 2778
