Answer :

Certainly, let's solve each part of the question step by step:

### Part (i)

We need to evaluate the expression:
[tex]\[ 26 + \{ -13 + 1 \} \][/tex]

Step-by-step solution:
1. First, solve the inner expression:
[tex]\[ -13 + 1 = -12 \][/tex]

2. Next, add this result to 26:
[tex]\[ 26 + (-12) = 14 \][/tex]

Hence, the value for part (i) is [tex]\( 14 \)[/tex].

### Part (ii)

We need to evaluate the expression:
[tex]\[ \{ -20 + 5 \} + \{ -5 + 2 \} \][/tex]

Step-by-step solution:
1. First, solve each inner expression:
[tex]\[ -20 + 5 = -15 \][/tex]
[tex]\[ -5 + 2 = -3 \][/tex]

2. Next, add these results together:
[tex]\[ -15 + (-3) = -18 \][/tex]

Hence, the value for part (ii) is [tex]\( -18 \)[/tex].

### Part (iii)

We need to evaluate the expression:
[tex]\[ \frac{46 \times 5 \times 0}{4} \][/tex]

Step-by-step solution:
1. First, perform the multiplication in the numerator:
[tex]\[ 46 \times 5 \times 0 = 0 \][/tex]

2. Next, divide the result by 4:
[tex]\[ \frac{0}{4} = 0.0 \][/tex]

Hence, the value for part (iii) is [tex]\( 0.0 \)[/tex].

### Summary

- The value for part (i) is [tex]\( 14 \)[/tex].
- The value for part (ii) is [tex]\( -18 \)[/tex].
- The value for part (iii) is [tex]\( 0.0 \)[/tex].

Answer:

hello

Step-by-step explanation:

i. 26 + (-13) + 1

=26+1 +(-13)

=27-13

= +14

ii. (-20) + 5 + (-5) + 2

(-20) +5 +(-5) +2

=(-20) +12

=(-18)

iii. (46 * 5 * 0 / 4)

=0

(Multiplying a number by 0 always results in zero (0).)
