Question

А) -35+(-9)=? б)-7+(-14)=? в)(-0,251+(-0,37))+(-0,2+(-0,152))=?

Answer 1

Вот, в "а" и "б" я написала просто ответ, а в "в" решение

Answer 2

Let's solve the given expressions step by step:

а) -35 + (-9) = ? To add two negative numbers, you simply add their absolute values and keep the negative sign. So, -35 + (-9) = -44.

б) -7 + (-14) = ? Similar to the previous example, you add the absolute values of the two negative numbers and keep the negative sign. -7 + (-14) = -21.

в) (-0.251 + (-0.37)) + (-0.2 + (-0.152)) = ? Start by adding the numbers within each pair of parentheses, and then add the results: (-0.251 + (-0.37)) = -0.621 (-0.2 + (-0.152)) = -0.352

Now, add the two results together: -0.621 + (-0.352) = -0.973

So, (-0.251 + (-0.37)) + (-0.2 + (-0.152)) = -0.973.
