(1) -2.3-(-8.8)

How can I sove this problem by multiply

(2) (1.3)(10)(-4)

1 subtract 95%sure

2 multiply 100%

On the first, you will have a negative number and a positive number. Subtract the smaller from the larger, and give the sign (-) of the larger to the result.

To solve problem (1) by subtracting, you need to follow these steps:

Step 1: Rewrite the subtraction sign as an addition sign and change the sign of the second number.
-2.3 - (-8.8) becomes -2.3 + 8.8.

Step 2: Perform the addition.
-2.3 + 8.8 = 6.5.

Therefore, the solution to problem (1) by subtracting is 6.5.

To solve problem (2) by multiplying, you need to follow these steps:

Step 1: Multiply the numbers together.
1.3 * 10 * -4 = -52.

Therefore, the solution to problem (2) by multiplying is -52.
