According to the order of operations, we will first solve the expression in parentheses.
We will solve the exercise vertically, making sure to align digits properly - ones under ones, tens under tens, and so on. Note that the decimal point is in place:
And we get the result:
Now we have the expression:
The above expression doesn't need to be calculated, we simply need to move the decimal point one place to the right, since we are multiplying by ten, meaning we're adding a tens place.
Therefore, we get the result:
\( 140-70= \)
The order of operations (PEMDAS) requires parentheses first! The expression means 'subtract first, then multiply the result.'
Line up the decimal points vertically! Write 1.4 above 0.3, making sure the decimal points align. Then subtract normally: 4 - 3 = 1, and 1 - 0 = 1, giving you 1.1.
Yes! When multiplying a decimal by 10, simply move the decimal point one place to the right. So (the decimal point moves from 1.1 to 11.0).
Double-check your work! Make sure you solved inside the parentheses first, aligned decimal points correctly, and moved the decimal point right when multiplying by 10.
Getting 9 means you probably calculated instead of 1.1. Remember: when subtracting decimals, 4 - 3 = 1 in the tenths place, and 1 - 0 = 1 in the ones place!
